Trait Mutability 

pub trait Mutability: MutabilityInner {
    type Ref<'a, T: 'a + ?Sized>: Deref<Target = T>;
    type Select<I, M>;

    // Required method
    fn select<I, M>(immut: I, mutable: M) -> Self::Select<I, M>;
}

Marks whether a type is mutable or immutable.

Required Associated Types

type Ref<'a, T: 'a + ?Sized>: Deref<Target = T>

The reference type associated with this mutability.

type Select<I, M>

Allows for choosing between one of two types based upon whether this is Const (in which case I is chosen) or Mut (in which case M is chosen).

Required Methods

fn select<I, M>(immut: I, mutable: M) -> Self::Select<I, M>

Allows for choosing between one of two values based upon whether this is Const (in which case immut is chosen) or Mut (in which case mut is chosen).

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.

Implementors

impl Mutability for Const

type Ref<'a, T: 'a + ?Sized> = &'a T

type Select<I, M> = I

impl Mutability for Mut

type Ref<'a, T: 'a + ?Sized> = &'a mut T

type Select<I, M> = M
