Functions

func MarshalSchema

func MarshalSchema(schema ent.Interface) (b []byte, err error)

MarshalSchema encodes the ent.Schema interface into a JSON that can be decoded into the Schema objects declared above.

Types

type Config

type Config struct {
	// Path is the path for the schema package.
	Path string
	// Names are the schema names to load. Empty means all schemas in the directory.
	Names []string
	// BuildFlags are forwarded to the package.Config when
	// loading the schema package.
	BuildFlags []string
}

Config holds the configuration for loading an ent/schema package.

func (*Config) Load

func (c *Config) Load() (*SchemaSpec, error)

Load loads the schemas package and build the Go plugin with this info.

Field represents an ent.Field that was loaded from a complied user package.

func NewField

func NewField(fd *field.Descriptor) (*Field, error)

NewField creates a loaded field from field descriptor.

type Index

type Index struct {
	Unique      bool           `json:"unique,omitempty"`
	Edges       []string       `json:"edges,omitempty"`
