Trait JSValue

pub trait JSValue<'a>: Sized {
    // Required method
    fn convert_to_rust(
        env: &'a JsEnv,
        js_value: *mut napi_value__,
    ) -> Result<Self, NjError>;

    // Provided method
    fn label() -> &'static str { ... }
}

Convert napi value to Rust value

Required Methods

fn convert_to_rust( env: &'a JsEnv, js_value: *mut napi_value__, ) -> Result<Self, NjError>

Provided Methods

fn label() -> &'static str

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
