Expand description
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

Required Associated Types§
Required Methods§
sourcefn from_inner(inner: Self::Inner) -> Self
fn from_inner(inner: Self::Inner) -> Self
Instantiates wrapper type with the inner data
sourcefn as_inner(&self) -> &Self::Inner
fn as_inner(&self) -> &Self::Inner
Returns reference to the inner representation for the wrapper type
sourcefn into_inner(self) -> Self::Inner
fn into_inner(self) -> Self::Inner
Unwraps the wrapper returning the inner type
Provided Methods§
Object Safety§
This trait is not object safe.
