Types

type Annotation

type Annotation struct {
	// The Table option allows overriding the default table
	// name that is generated by ent. For example:
	//
	//	entsql.Annotation{
	//		Table: "Users",
	//	}
	//
	Table string `json:"table,omitempty"`

	// Charset defines the character-set of the table. For example:
	//
	//	entsql.Annotation{
	//		Charset: "utf8mb4",
	//	}
	//
	Charset string `json:"charset,omitempty"`

	// Collation defines the collation of the table (a set of rules for comparing
	// characters in a character set). For example:
	//
	//	entsql.Annotation{
	//		Collation: "utf8mb4_bin",
	//	}
	//
	Collation string `json:"collation,omitempty"`

	// Options defines the additional table options. For example:
	//
	//	entsql.Annotation{
	//		Options: "ENGINE = INNODB",
	//	}
	//
	Options string `json:"options,omitempty"`

	// Size defines the column size in the generated schema. For example:
	//
	//	entsql.Annotation{
	//		Size: 128,
	//	}
	//
	Size int64 `json:"size,omitempty"`

	// Incremental defines the autoincremental behavior of a column. For example:
	//
	//  incrementalEnabled := true
	//  entsql.Annotation{
	//      Incremental: &incrementalEnabled,
	//  }
	//
	// By default, this value is nil defaulting to whatever best fits each scenario.
	//
	Incremental *bool `json:"incremental,omitempty"`
}
