Struct BindOptions

pub struct BindOptions<'a, 'cx: 'a> { /* private fields */ }

A builder for making a JavaScript function call like parseInt("42").

The builder methods make it convenient to assemble the call from parts:

let x: f64 = parse_int
    .bind(&mut cx)
    .arg("42")?
    .call()?;

Implementations

impl<'a, 'cx: 'a> BindOptions<'a, 'cx>

pub fn this<T: TryIntoJs<'cx>>(&mut self, this: T) -> NeonResult<&mut Self>

Set the value of this for the function call.

pub fn args<A: TryIntoArguments<'cx>>(&mut self, a: A) -> NeonResult<&mut Self>

Replaces the arguments list with the given arguments.

pub fn args_with<R, F>(&mut self, f: F) -> NeonResult<&mut Self>

where R: TryIntoArguments<'cx>, F: FnOnce(&mut Cx<'cx>) -> R,

Replaces the arguments list with a list computed from a closure.

pub fn arg<A: TryIntoJs<'cx>>(&mut self, a: A) -> NeonResult<&mut Self>

Add an argument to the arguments list.

pub fn arg_with<R, F>(&mut self, f: F) -> NeonResult<&mut Self>

where R: TryIntoJs<'cx>, F: FnOnce(&mut Cx<'cx>) -> R,

Add an argument to the arguments list, computed from a closure.

pub fn call<R: TryFromJs<'cx>>(&mut self) -> NeonResult<R>

Make the function call. If the function returns without throwing, the result value is converted to a Rust value with TryFromJs::from_js.

pub fn construct<R: TryFromJs<'cx>>(&mut self) -> NeonResult<R>

Make the function call as a constructor. If the function returns without throwing, the result value is converted to a Rust value with TryFromJs::from_js.

pub fn exec(&mut self) -> NeonResult<()>

Make the function call for side effect, discarding the result value. This method is preferable to call() when the result value isn’t needed, since it doesn’t require specifying a result type.
