Struct shred::Fetch

pub struct Fetch<'a, T: 'a> { /* private fields */ }

Expand description

Allows to fetch a resource in a system immutably.

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

Type parameters

T: The type of the resource

Trait Implementations

source

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

type Target = T

source

impl<'a, T, F> From<Fetch<'a, T>> for Read<'a, T, F>

source

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