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<'a, R>( js_value: &'a R, ) -> Result<<Self as RefFromWasmAbi>::Anchor, Error>
where R: AsRef<JsValue> + 'a,

Obtain safe reference from JsValue

source

fn try_long_ref_from_js_value<'a, R>( js: &'a R, ) -> Result<<Self as LongRefFromWasmAbi>::Anchor, Error>
where R: AsRef<JsValue> + 'a,

Obtain safe long reference from JsValue

Provided Methods§

source

fn try_ref_from_js_value_as_cast<'a, R>( js_value: &'a R, ) -> Result<Cast<'a, Self>, Error>
where R: AsRef<JsValue> + 'a,

source

fn try_long_ref_from_js_value_as_cast<'a, R>( js: &'a R, ) -> Result<Cast<'_, Self>, Error>
where R: AsRef<JsValue> + 'a,

Object Safety§

This trait is not object safe.
