Struct ResourceLoadersContainer 

pub struct ResourceLoadersContainer { /* private fields */ }

Container for resource loaders.

Implementations

impl ResourceLoadersContainer

pub fn new() -> Self

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>

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

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

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

pub fn is_supported_resource(&self, path: &Path) -> bool

Returns true if there’s at least one resource loader, that supports the extension of the file at the given path.

pub fn loader_for_data_type( &self, data_type_uuid: Uuid, ) -> Option<&dyn ResourceLoader>

Tries to fina a loader for the specified data type uuid.

pub fn is_extension_matches_type<T>(&self, path: &Path) -> bool

where T: TypedResourceData,

Checks if there’s a resource loader for the given path and the data type produced by the loader matches the given type T.

pub fn loader_for(&self, path: &Path) -> Option<&dyn ResourceLoader>

Checks if there’s a loader for the given path.

Trait Implementations

impl Default for ResourceLoadersContainer

fn default() -> ResourceLoadersContainer

Returns the “default value” for a type.
