Trait wasm_bindgen::convert::TryFromJsValue

pub trait TryFromJsValue: Sized {
    type Error;

    // Required method
    fn try_from_js_value(value: JsValue) -> Result<Self, Self::Error>;
}

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

type Error

The type returned in the event of a conversion error.

Required Methods

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

Performs the conversion.

Object Safety

This trait is not object safe.
