Trait VecLike 

pub trait VecLike: IntoIterator<Item = Self::T> + Extend<Self::T> {
    type T;

    // Required methods
    fn with_capacity(n: usize) -> Self
       where Self: Sized;
    fn push(&mut self, x: Self::T);
    fn pop(&mut self) -> Option<Self::T>;

    // Provided methods
    fn new() -> Self
       where Self: Sized { ... }
    fn map_elements<T2, E2>(self, f: impl FnMut(Self::T) -> T2) -> E2
       where E2: VecLike<T = T2>,
             Self: Sized { ... }
    fn is_empty(&self) -> bool { ... }
}

A trait for mutable growable vectors.

Required Associated Types

type T

The type of input elements.

Required Methods

fn with_capacity(n: usize) -> Self

where Self: Sized,

Create an instance of this container with at least n elements allocated.

fn push(&mut self, x: Self::T)

Push an element to the end.

fn pop(&mut self) -> Option<Self::T>

Pop an element from the end.

fn len(&self) -> usize

The number of elements.

fn as_slice(&self) -> &[Self::T]

A contiguous slice of memory referring to the elements.

Provided Methods

fn new() -> Self

where Self: Sized,

Create an instance of this container without allocating any memory.

Also see ConstDefault for an orthogonal trait for const instances.

fn map_elements<T2, E2>(self, f: impl FnMut(Self::T) -> T2) -> E2

where E2: VecLike<T = T2>, Self: Sized,

Convert an instance of this vector into another type.

fn is_empty(&self) -> bool

Whether there are any elements.

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.
