Trait SplitAtWhile

pub trait SplitAtWhile {
    type Item;

    // Required method
    fn split_at_while<F>(&self, f: F) -> (&Self, &Self)
       where F: FnMut(&Self::Item) -> bool;
}

Required Associated Types

type Item

Required Methods

fn split_at_while<F>(&self, f: F) -> (&Self, &Self)

where F: FnMut(&Self::Item) -> bool,

Splits a slice at the first point after which f returns false. Usually used to segment input according to character categories.

e.g. 1. part while f(x) == true, then 2. part

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.
