Trait IntoArgs 

pub trait IntoArgs<'js> {
    // Required methods
    fn num_args(&self) -> usize;
    fn into_args(self, args: &mut Args<'js>) -> Result<()>;

    // Provided methods
    fn apply<R>(self, function: &Function<'js>) -> Result<R>
       where R: FromJs<'js>,
             Self: Sized { ... }

       where Self: Sized { ... }
    fn construct<R>(self, function: &Constructor<'js>) -> Result<()>
       where Self: Sized { ... }
}

A trait for converting a tuple of values into a list arguments.

Required Methods

fn num_args(&self) -> usize

The number of arguments this value produces.

fn into_args(self, args: &mut Args<'js>) -> Result<()>

Convert the value into an argument.

Provided Methods

fn apply<R>(self, function: &Function<'js>) -> Result<R>

where R: FromJs<'js>, Self: Sized,

fn defer<R>(self, function: Function<'js>) -> Result<()>

where Self: Sized,

fn construct<R>(self, function: &Constructor<'js>) -> Result<()>

where Self: Sized,

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
