Expand description

CastFromJs trait is automatically implemented by deriving the CastFromJs derive macro. This trait provides functions for accessing Rust references from the WASM ABI.

Required Methods§

source

fn try_ref_from_js_value( js: impl AsRef<JsValue>, ) -> Result<<Self as RefFromWasmAbi>::Anchor, Error>

Obtain safe reference from JsValue

source

fn try_long_ref_from_js_value( js: impl AsRef<JsValue>, ) -> Result<<Self as LongRefFromWasmAbi>::Anchor, Error>

Obtain safe long reference from JsValue

Provided Methods§

source

fn try_ref_from_js_value_as_cast( js: impl AsRef<JsValue>, ) -> Result<Cast<Self>, Error>

source

fn try_long_ref_from_js_value_as_cast( js: impl AsRef<JsValue>, ) -> Result<Cast<Self>, Error>

Object Safety§

This trait is not object safe.
