Trait moveit::new::Emplace

pub trait Emplace<T>: Sized {
    fn try_emplace<N: TryNew<Output = T>>(n: N) -> Result<Pin<Self>, N::Error>;

    fn emplace<N: New<Output = T>>(n: N) -> Pin<Self> { ... }
}

A pointer type with a stable address that a New may be used to construct a value with.

This enables an emplace() method for Box, Rc, and Arc. Users are encouraged to implement this function for their own heap-allocated smart pointers.

Required methods

fn try_emplace<N: TryNew<Output = T>>(n: N) -> Result<Pin<Self>, N::Error>

Constructs a new smart pointer and tries to emplace n into its storage.

Provided methods

fn emplace<N: New<Output = T>>(n: N) -> Pin<Self>

Constructs a new smart pointer and emplaces n into its storage.
