Return a value-bound field handle, or null when no such field exists.

function

Whether this value's runtime class declares a field called name. false when the runtime type is not a class.

function

list_fields

(self) -> reflect.class.Field[]

Reflected fields bound to this value for Field.value<T>().

function

(self) -> string

The rendered name of this value's concrete runtime type.

function
