Trait ForEach

pub trait ForEach: Iterator {
    // Required method
    fn foreach<O, F>(&mut self, f: F)
       where O: Into<Continue>,
             F: FnMut(Self::Item, &mut Self) -> O;
}

Trait to simplify usage of iterator inside iteration loop.

This trait is implemented for all iterators by default.

Required Methods

fn foreach<O, F>(&mut self, f: F)

where O: Into<Continue>, F: FnMut(Self::Item, &mut Self) -> O,

Iterates over all items and executes given closure.

This allows you to use iterator inside iteration loop, which is not posible when using for-in loop.

See crate-level docs for examples

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.
