Trait Projection 

pub trait Projection<E> {
    const LEN: usize;

    // Required method
    fn try_for_each<F>(
        &self,
        visit: impl FnMut(&E) -> Result<(), F>,
    ) -> Result<(), F>;
}

Required Associated Constants

const LEN: usize

Required Methods

fn try_for_each<F>( &self, visit: impl FnMut(&E) -> Result<(), F>, ) -> Result<(), F>

Dyn Compatibility

This trait is not dyn compatible.

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