reflect.InvalidArgumentError

Thrown by `reflect.call_any` when the supplied arguments or returned value do not fit its runtime signature. `argument` names the offending key (`$argN` placeholders included); a return mismatch names the `reflect.call_any return value` boundary. An ill-typed value reports the expected and actual types; a missing required parameter reports the parameter's type and `never`; a key naming no parameter reports the callee's whole function type and the value's type.

Implementations

reflect.AnyClass for T

Instance methods

function

attributes

(self) -> reflect.Meta

The class declaration's schema metadata, or empty metadata when the runtime type is not a class.

function

get

<T>(self, name: string) -> T | null throws reflect.errors.TypeMismatch

Read a field as T. A missing field returns null; use has_field to distinguish that case from a present field whose value is null.

function

get_field

(self, name: string) -> reflect.class.Field | null

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

function

has_field

(self, name: string) -> bool

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

name

(self) -> string

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

function

type

(self) -> reflect.Type

This value's concrete runtime type.
