Trait Implementations§

Source§

impl<'cx> TryFromJs<'cx> for Buffer

Source§

type Error = TypeExpected<JsBuffer>

Source§

fn try_from_js( cx: &mut Cx<'cx>, v: Handle<'cx, JsValue>, ) -> NeonResult<Result<Self, Self::Error>>

Extract this Rust type from a JavaScript value
Source§

fn from_js(cx: &mut Cx<'cx>, v: Handle<'cx, JsValue>) -> NeonResult<Self>

Source§

type Value = JsBuffer

The type of JavaScript value that will be created
Source§

fn try_into_js(self, cx: &mut Cx<'cx>) -> JsResult<'cx, Self::Value>
