Container for resource loaders.

Implementations

impl ResourceLoadersContainer

pub fn new() -> ResourceLoadersContainer

Creates new empty resource loaders container.

pub fn set<T>(&mut self, loader: T) -> Option<T>

where T: ResourceLoader,

Adds new resource loader or replaces existing. There could be only one loader of a given type at the same time. You can use this method to replace resource loaders with your own loaders.

pub fn try_replace<Prev, New>(&mut self, new_loader: New) -> Option<Prev>

where Prev: ResourceLoader, New: ResourceLoader,

Searches for an instance of a resource loader of type Prev and replaces it with an other instance of a type New.

pub fn find<T>(&self) -> Option<&T>

where T: ResourceLoader,

Tries to find an instance of a resource loader of the given type `T.

pub fn find_mut<T>(&mut self) -> Option<&mut T>

where T: ResourceLoader,

Tries to find an instance of a resource loader of the given type `T.

pub fn len(&self) -> usize

Returns total amount of resource loaders in the container.

pub fn is_empty(&self) -> bool

Return true if the container contains no resource loaders.

pub fn iter(&self) -> impl Iterator<Item = &(dyn ResourceLoader + 'static)>

Returns an iterator yielding shared references to “untyped” resource loaders.

pub fn iter_mut( &mut self, ) -> impl Iterator<Item = &mut (dyn ResourceLoader + 'static)>

Returns an iterator yielding mutable references to “untyped” resource loaders.

Trait Implementations

impl Default for ResourceLoadersContainer

fn default() -> ResourceLoadersContainer

Returns the “default value” for a type.
