type Dehydrate ¶

type Dehydrate func(x interface{}) (*Struct, error)

Called by packer to let caller send custom object as structs not known by packstream. Used as a convenience to let the caller be lazy and just send in data and be called when packstream doesn't know what it is instead of checking all data up front.

type Hydrate func(tag StructTag, fields []interface{}) (interface{}, error)

Called by unpacker to let receiver check all fields and let the receiver return an hydrated instance or an error if any of the fields or number of fields are different expected.

type IllegalFormatError ¶

type IllegalFormatError struct {
	// contains filtered or unexported fields
