Functions

func All added in v0.7.0 

func All(validators ...validator.Number) validator.Number

All returns a validator which ensures that any configured attribute value attribute value validates against all the given validators.

Use of All is only necessary when used in conjunction with Any or AnyWithAllWarnings as the Validators field automatically applies a logical AND.

Example 
package main

import (
	"math/big"

	"github.com/hashicorp/terraform-plugin-framework-validators/numbervalidator"
	"github.com/hashicorp/terraform-plugin-framework/datasource/schema"
	"github.com/hashicorp/terraform-plugin-framework/schema/validator"
)

func main() {
	// Used within a Schema method of a DataSource, Provider, or Resource
	_ = schema.Schema{
		Attributes: map[string]schema.Attribute{
			"example_attr": schema.NumberAttribute{
				Required: true,
				Validators: []validator.Number{
					// Validate this Number value must either be:
					//  - 1.0
					//  - 2.0, but not 3.0
					numbervalidator.Any(
						numbervalidator.OneOf(big.NewFloat(1.0)),
						numbervalidator.All(
							numbervalidator.OneOf(big.NewFloat(2.0)),
							numbervalidator.NoneOf(big.NewFloat(3.0)),
						),
					),
				},
			},
		},
	}
}

func AlsoRequires added in v0.7.0 

func AlsoRequires(expressions ...path.Expression) validator.Number

AlsoRequires checks that a set of path.Expression has a non-null value, if the current attribute or block also has a non-null value.

This implements the validation logic declaratively within the schema. Refer to [datasourcevalidator.RequiredTogether], [providervalidator.RequiredTogether], or [resourcevalidator.RequiredTogether] for declaring this type of validation outside the schema definition.

Relative path.Expression will be resolved using the attribute or block being validated.

Example 
package main

import (
	"github.com/hashicorp/terraform-plugin-framework-validators/numbervalidator"
	"github.com/hashicorp/terraform-plugin-framework/datasource/schema"
	"github.com/hashicorp/terraform-plugin-framework/path"
	"github.com/hashicorp/terraform-plugin-framework/schema/validator"
)

func main() {
	// Used within a Schema method of a DataSource, Provider, or Resource
	_ = schema.Schema{
		Attributes: map[string]schema.Attribute{
			"example_attr": schema.NumberAttribute{
				Optional: true,
				Validators: []validator.Number{
					// Validate this attribute must be configured with other_attr.
					numbervalidator.AlsoRequires(path.Expressions{
						path.MatchRoot("other_attr"),
					}...),
				},
			},
			"other_attr": schema.StringAttribute{
				Optional: true,
			},
		},
	}
}

Output:

func Any added in v0.7.0 

func Any(validators ...validator.Number) validator.Number

Any returns a validator which ensures that any configured attribute value passes at least one of the given validators.

To prevent practitioner confusion should non-passing validators have conflicting logic, only warnings from the passing validator are returned. Use AnyWithAllWarnings() to return warnings from non-passing validators as well.

Example 
package main

import (
	"math/big"

	"github.com/hashicorp/terraform-plugin-framework-validators/numbervalidator"
	"github.com/hashicorp/terraform-plugin-framework/datasource/schema"
	"github.com/hashicorp/terraform-plugin-framework/schema/validator"
)

func main() {
	// Used within a Schema method of a DataSource, Provider, or Resource
	_ = schema.Schema{
		Attributes: map[string]schema.Attribute{
			"example_attr": schema.NumberAttribute{
				Required: true,
				Validators: []validator.Number{
					// Validate this Number value must either be:
					//  - 1.0
					//  - Not 2.0
					numbervalidator.Any(
						numbervalidator.OneOf(big.NewFloat(1.0)),
						numbervalidator.NoneOf(big.NewFloat(2.0)),
					),
				},
			},
		},
	}
}

Output:

func AnyWithAllWarnings added in v0.7.0 

func AnyWithAllWarnings(validators ...validator.Number) validator.Number

AnyWithAllWarnings returns a validator which ensures that any configured attribute value passes at least one of the given validators. This validator returns all warnings, including failed validators.

Use Any() to return warnings only from the passing validator.

Example 
package main

import (
	"math/big"

	"github.com/hashicorp/terraform-plugin-framework-validators/numbervalidator"
	"github.com/hashicorp/terraform-plugin-framework/datasource/schema"
	"github.com/hashicorp/terraform-plugin-framework/schema/validator"
)

func main() {
	// Used within a Schema method of a DataSource, Provider, or Resource
	_ = schema.Schema{
		Attributes: map[string]schema.Attribute{
			"example_attr": schema.NumberAttribute{
				Required: true,
				Validators: []validator.Number{
					// Validate this Number value must either be:
					//  - 1.0
					//  - Not 2.0
					numbervalidator.AnyWithAllWarnings(
						numbervalidator.OneOf(big.NewFloat(1.0)),
						numbervalidator.NoneOf(big.NewFloat(2.0)),
					),
				},
			},
		},
	}
}

Output:

func AtLeastOneOf added in v0.7.0 

func AtLeastOneOf(expressions ...path.Expression) validator.Number

AtLeastOneOf checks that of a set of path.Expression, including the attribute this validator is applied to, at least one has a non-null value.

This implements the validation logic declaratively within the tfsdk.Schema. Refer to [datasourcevalidator.AtLeastOneOf], [providervalidator.AtLeastOneOf], or [resourcevalidator.AtLeastOneOf] for declaring this type of validation outside the schema definition.

Any relative path.Expression will be resolved using the attribute being validated.

Example 
package main

import (
	"github.com/hashicorp/terraform-plugin-framework-validators/numbervalidator"
	"github.com/hashicorp/terraform-plugin-framework/datasource/schema"
	"github.com/hashicorp/terraform-plugin-framework/path"
	"github.com/hashicorp/terraform-plugin-framework/schema/validator"
)

func main() {
	// Used within a Schema method of a DataSource, Provider, or Resource
	_ = schema.Schema{
		Attributes: map[string]schema.Attribute{
			"example_attr": schema.NumberAttribute{
				Optional: true,
				Validators: []validator.Number{
					// Validate at least this attribute or other_attr should be configured.
					numbervalidator.AtLeastOneOf(path.Expressions{
						path.MatchRoot("other_attr"),
					}...),
				},
			},
			"other_attr": schema.StringAttribute{
				Optional: true,
			},
		},
	}
}

Output:

func ConflictsWith added in v0.7.0 

func ConflictsWith(expressions ...path.Expression) validator.Number

ConflictsWith checks that a set of path.Expression, including the attribute the validator is applied to, do not have a value simultaneously.

This implements the validation logic declaratively within the schema. Refer to [datasourcevalidator.Conflicting], [providervalidator.Conflicting], or [resourcevalidator.Conflicting] for declaring this type of validation outside the schema definition.

Relative path.Expression will be resolved using the attribute being validated.

Example 
package main

import (
	"github.com/hashicorp/terraform-plugin-framework-validators/numbervalidator"
	"github.com/hashicorp/terraform-plugin-framework/datasource/schema"
	"github.com/hashicorp/terraform-plugin-framework/path"
	"github.com/hashicorp/terraform-plugin-framework/schema/validator"
)

func main() {
	// Used within a Schema method of a DataSource, Provider, or Resource
	_ = schema.Schema{
		Attributes: map[string]schema.Attribute{
			"example_attr": schema.NumberAttribute{
				Optional: true,
				Validators: []validator.Number{
					// Validate this attribute must not be configured with other_attr.
					numbervalidator.ConflictsWith(path.Expressions{
						path.MatchRoot("other_attr"),
					}...),
				},
			},
			"other_attr": schema.StringAttribute{
				Optional: true,
			},
		},
	}
}

Output:

func ExactlyOneOf added in v0.7.0 

func ExactlyOneOf(expressions ...path.Expression) validator.Number

ExactlyOneOf checks that of a set of path.Expression, including the attribute the validator is applied to, one and only one attribute has a value. It will also cause a validation error if none are specified.

This implements the validation logic declaratively within the schema. Refer to [datasourcevalidator.ExactlyOneOf], [providervalidator.ExactlyOneOf], or [resourcevalidator.ExactlyOneOf] for declaring this type of validation outside the schema definition.

Relative path.Expression will be resolved using the attribute being validated.

Example 
package main

import (
	"github.com/hashicorp/terraform-plugin-framework-validators/numbervalidator"
	"github.com/hashicorp/terraform-plugin-framework/datasource/schema"
	"github.com/hashicorp/terraform-plugin-framework/path"
	"github.com/hashicorp/terraform-plugin-framework/schema/validator"
)

func main() {
	// Used within a Schema method of a DataSource, Provider, or Resource
	_ = schema.Schema{
		Attributes: map[string]schema.Attribute{
			"example_attr": schema.NumberAttribute{
				Optional: true,
				Validators: []validator.Number{
					// Validate only this attribute or other_attr is configured.
					numbervalidator.ExactlyOneOf(path.Expressions{
						path.MatchRoot("other_attr"),
					}...),
				},
			},
			"other_attr": schema.StringAttribute{
				Optional: true,
			},
		},
	}
}

Output:

func NoneOf 

func NoneOf(values ...*big.Float) validator.Number

NoneOf checks that the Number held in the attribute is none of the given `values`.

Example 
package main

import (
	"math/big"

	"github.com/hashicorp/terraform-plugin-framework-validators/numbervalidator"
	"github.com/hashicorp/terraform-plugin-framework/datasource/schema"
	"github.com/hashicorp/terraform-plugin-framework/schema/validator"
)

func main() {
	// Used within a Schema method of a DataSource, Provider, or Resource
	_ = schema.Schema{
		Attributes: map[string]schema.Attribute{
			"example_attr": schema.NumberAttribute{
				Required: true,
				Validators: []validator.Number{
					// Validate number value must not be 1.2, 2.4, or 4.8
					numbervalidator.NoneOf(
						[]*big.Float{
							big.NewFloat(1.2),
							big.NewFloat(2.4),
							big.NewFloat(4.8),
						}...,
					),
				},
			},
		},
	}
}

Output:

func OneOf 

func OneOf(values ...*big.Float) validator.Number

OneOf checks that the Number held in the attribute is none of the given `values`.

Example 
package main

import (
	"math/big"
