Types

type FieldData

type FieldData struct {
	Raw    map[string]interface{}
	Schema map[string]*FieldSchema
}

FieldData contains the raw data and the schema that the data should adhere to

func (*FieldData) Get

func (d *FieldData) Get(k string) interface{}

Get gets the value for the given field. If the key is an invalid field, FieldData will panic. If you want a safer version of this method, use GetOk. If the field k is not set, the default value (if set) will be returned, otherwise the zero value will be returned.

func (*FieldData) GetOk

func (d *FieldData) GetOk(k string) (interface{}, bool)

GetOk gets the value for the given field. The second return value will be false if the key is invalid or the key is not set at all.

func (*FieldData) GetOkErr

func (d *FieldData) GetOkErr(k string) (interface{}, bool, error)

GetOkErr is the most conservative of all the Get methods. It returns whether key is set or not, but also an error value. The error value is non-nil if the field doesn't exist or there was an error parsing the field value.

func (*FieldData) Validate

func (d *FieldData) Validate() error

Validate cycles through the raw data and validates conversions in the schema. It also checks for the existence and value of required fields.

type FieldSchema

type FieldSchema struct {
	Type        FieldType
	Default     interface{}
	Description string
	Required    bool
}

FieldSchema is a basic schema to describe the format of a configuration field

func (*FieldSchema) DefaultOrZero

func (s *FieldSchema) DefaultOrZero() interface{}

DefaultOrZero returns the default value if it is set, or otherwise the zero value of the type.

type FieldType

type FieldType uint

FieldType is the enum of types that a field can be.

const (
	TypeInvalid FieldType = 0
	TypeString  FieldType = iota
	TypeInt
	TypeBool
	TypeMap
	TypeArray
)

func (FieldType) String

func (t FieldType) String() string

func (FieldType) Zero

func (t FieldType) Zero() interface{}
