Struct shred::Write

pub struct Write<'a, T: 'a, F = DefaultProvider> { /* fields omitted */ }

Allows to fetch a resource in a system mutably.

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

Type parameters

• T: The type of the resource
• F: The setup handler (default: DefaultProvider)

Trait Implementations

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

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

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

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

Mutably dereferences the value.

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

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

Performs the conversion.

impl<'a, T, F> SystemData<'a> for Write<'a, T, F> where
    T: Resource,
    F: SetupHandler<T>, 

fn setup(res: &mut Resources)

Sets up Resources for fetching this system data.

fn fetch(res: &'a Resources) -> Self

Creates a new resource bundle by fetching the required resources from the [Resources] struct.

fn reads() -> Vec<ResourceId>

A list of [ResourceId]s the bundle needs read access to in order to build the target resource bundle.

fn writes() -> Vec<ResourceId>

A list of [ResourceId]s the bundle needs write access to in order to build the target resource bundle.
