Struct amethyst::ecs::shred::FetchMut

pub struct FetchMut<'a, T> where
    T: 'a,  { /* fields omitted */ }

Allows to fetch a resource in a system mutably.

If the resource isn't strictly required, you should use Option<FetchMut<T>>.

Type parameters

• T: The type of the resource

Trait Implementations

impl<'a, T> Deref for FetchMut<'a, T> where     T: Resource,

type Target = T

The resulting type after dereferencing.

Important traits for &'a mut R

impl<'a, R> Read for &'a mut R where
    R: Read + ?Sized, impl<'a, W> Write for &'a mut W where
    W: Write + ?Sized, impl<'a, I> Iterator for &'a mut I where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;

fn deref(&self) -> &T

Dereferences the value.

impl<'a, T, F> From<FetchMut<'a, T>> for Write<'a, T, F>

fn from(inner: FetchMut<'a, T>) -> Write<'a, T, F>

Performs the conversion.

impl<'a, T> DerefMut for FetchMut<'a, T> where     T: Resource,

Important traits for &'a mut R

impl<'a, R> Read for &'a mut R where
    R: Read + ?Sized, impl<'a, W> Write for &'a mut W where
    W: Write + ?Sized, impl<'a, I> Iterator for &'a mut I where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;

fn deref_mut(&mut self) -> &mut T

Mutably dereferences the value.
