Trait VecExt

pub trait VecExt<T> {
    // Required methods
    fn any<F: Fn(&T) -> bool>(&self, f: F) -> bool;
    fn fold<F, U>(&self, f: F, init: U) -> U
       where F: Fn(U, &T) -> U;
    fn into_first(self) -> Option<T>;
    fn into_last(self) -> Option<T>;
}

Required Methods

fn any<F: Fn(&T) -> bool>(&self, f: F) -> bool

fn fold<F, U>(&self, f: F, init: U) -> U

where F: Fn(U, &T) -> U,

fn into_first(self) -> Option<T>

fn into_last(self) -> Option<T>

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.
