Trait amplify::Wrapper[−][src]

pub trait Wrapper {
    type Inner: Clone;
    fn from_inner(inner: Self::Inner) -> Self;

    fn as_inner(&self) -> &Self::Inner;

    fn as_inner_mut(&mut self) -> &mut Self::Inner;

    fn into_inner(self) -> Self::Inner;

    fn to_inner(&self) -> Self::Inner { ... }

    fn copy(&self) -> Self
    where
        Self: Sized,
        Self::Inner: Copy,
    { ... }
}

Trait defining wrapped types (“newtypes” in rust terminology). Wrapped types are used for allowing implemeting foreign traits to foreign types: https://doc.rust-lang.org/stable/rust-by-example/generics/new_types.html

Trait defines convenient methods for accessing inner data, construct and deconstruct newtype. It also serves as a marker trait for newtypes.

The trait works well with #[derive(Wrapper)] from amplify_derive crate

Associated Types

Required methods

fn from_inner(inner: Self::Inner) -> Self[src]

Instantiates wrapper type with the inner data

fn as_inner(&self) -> &Self::Inner[src]

Returns reference to the inner representation for the wrapper type

fn as_inner_mut(&mut self) -> &mut Self::Inner[src]

Returns a mutable reference to the inner representation for the wrapper type

fn into_inner(self) -> Self::Inner[src]

Unwraps the wrapper returning the inner type

Provided methods

fn to_inner(&self) -> Self::Inner[src]

Clones inner data of the wrapped type and return them

fn copy(&self) -> Self where
    Self: Sized,
    Self::Inner: Copy, [src]

Copies the wrapped type
