Expand description

TryFromJsValue is a trait for converting a JavaScript value (JsValue) into a Rust type. It is used by the wasm_bindgen proc-macro to allow conversion to user types.

Types implementing this trait must specify their conversion logic from JsValue to the Rust type, handling any potential errors that may occur during the conversion process.

Required Associated Types§

Required Methods§

source

fn try_from_js_value(value: JsValue) -> Result<Self, Self::Error>
