pub struct Resources { /* private fields */ }
Expand description
Resources container. Shared resources stored here can be retrieved in systems.
Implementations
sourceimpl Resources
impl Resources
sourcepub fn sync(&mut self) -> SyncResources<'_>
pub fn sync(&mut self) -> SyncResources<'_>
Creates an accessor to resources which are Send and Sync, which itself can be sent between threads.
sourcepub fn contains<T: Resource>(&self) -> bool
pub fn contains<T: Resource>(&self) -> bool
Returns true
if type T
exists in the store. Otherwise, returns false
.
sourcepub fn insert<T: Resource>(&mut self, value: T)
pub fn insert<T: Resource>(&mut self, value: T)
Inserts the instance of T
into the store. If the type already exists, it will be silently
overwritten. If you would like to retain the instance of the resource that already exists,
call remove
first to retrieve it.
sourcepub fn remove<T: Resource>(&mut self) -> Option<T>
pub fn remove<T: Resource>(&mut self) -> Option<T>
Removes the type T
from this store if it exists.
Returns
If the type T
was stored, the inner instance of T is returned. Otherwise,
None`.
sourcepub fn get<T: Resource>(&self) -> Option<AtomicRef<'_, T>>
pub fn get<T: Resource>(&self) -> Option<AtomicRef<'_, T>>
Retrieve an immutable reference to T
from the store if it exists. Otherwise, return None
.
Panics
Panics if the resource is already borrowed mutably.
sourcepub fn get_mut<T: Resource>(&self) -> Option<AtomicRefMut<'_, T>>
pub fn get_mut<T: Resource>(&self) -> Option<AtomicRefMut<'_, T>>
Retrieve a mutable reference to T
from the store if it exists. Otherwise, return None
.
sourcepub fn get_or_insert_with<T: Resource, F: FnOnce() -> T>(
&mut self,
f: F
) -> AtomicRef<'_, T>
pub fn get_or_insert_with<T: Resource, F: FnOnce() -> T>(
&mut self,
f: F
) -> AtomicRef<'_, T>
Attempts to retrieve an immutable reference to T
from the store. If it does not exist,
the closure f
is called to construct the object and it is then inserted into the store.
sourcepub fn get_mut_or_insert_with<T: Resource, F: FnOnce() -> T>(
&mut self,
f: F
) -> AtomicRefMut<'_, T>
pub fn get_mut_or_insert_with<T: Resource, F: FnOnce() -> T>(
&mut self,
f: F
) -> AtomicRefMut<'_, T>
Attempts to retrieve a mutable reference to T
from the store. If it does not exist,
the closure f
is called to construct the object and it is then inserted into the store.
sourcepub fn get_or_insert<T: Resource>(&mut self, value: T) -> AtomicRef<'_, T>
pub fn get_or_insert<T: Resource>(&mut self, value: T) -> AtomicRef<'_, T>
Attempts to retrieve an immutable reference to T
from the store. If it does not exist,
the provided value is inserted and then a reference to it is returned.
sourcepub fn get_mut_or_insert<T: Resource>(
&mut self,
value: T
) -> AtomicRefMut<'_, T>
pub fn get_mut_or_insert<T: Resource>(
&mut self,
value: T
) -> AtomicRefMut<'_, T>
Attempts to retrieve a mutable reference to T
from the store. If it does not exist,
the provided value is inserted and then a reference to it is returned.
sourcepub fn get_or_default<T: Resource + Default>(&mut self) -> AtomicRef<'_, T>
pub fn get_or_default<T: Resource + Default>(&mut self) -> AtomicRef<'_, T>
Attempts to retrieve an immutable reference to T
from the store. If it does not exist,
the default constructor for T
is called.
T
must implement Default
for this method.
sourcepub fn get_mut_or_default<T: Resource + Default>(
&mut self
) -> AtomicRefMut<'_, T>
pub fn get_mut_or_default<T: Resource + Default>(
&mut self
) -> AtomicRefMut<'_, T>
Attempts to retrieve a mutable reference to T
from the store. If it does not exist,
the default constructor for T
is called.
T
must implement Default
for this method.
