Struct freya::prelude::SyncStorage

pub struct SyncStorage(/* private fields */);

A thread safe storage. This is slower than the unsync storage, but allows you to share the value between threads.

Trait Implementations

impl AnyStorage for SyncStorage

type Ref<R: 'static + ?Sized> = GenerationalRef<MappedRwLockReadGuard<'static, RawRwLock, R>>

The reference this storage type returns.

type Mut<W: 'static + ?Sized> = GenerationalRefMut<MappedRwLockWriteGuard<'static, RawRwLock, W>>

The mutable reference this storage type returns.

fn try_map<I, U>( ref_: <SyncStorage as AnyStorage>::Ref<I>, f: impl FnOnce(&I) -> Option<&U> ) -> Option<<SyncStorage as AnyStorage>::Ref<U>>

where U: 'static + ?Sized, I: ?Sized,

Try to map the ref.

fn try_map_mut<I, U>( mut_ref: <SyncStorage as AnyStorage>::Mut<I>, f: impl FnOnce(&mut I) -> Option<&mut U> ) -> Option<<SyncStorage as AnyStorage>::Mut<U>>

where U: 'static + ?Sized, I: ?Sized,

Try to map the mutable ref.

fn data_ptr(&self) -> *const ()

Get the data pointer. No guarantees are made about the data pointer. It should only be used for debugging.

fn manually_drop(&self) -> bool

Drop the value from the storage. This will return true if the value was taken.

fn claim() -> MemoryLocation<SyncStorage>

Claim a new memory location. This will either create a new memory location or recycle an old one.

fn recycle(location: &MemoryLocation<SyncStorage>)

Recycle a memory location. This will drop the memory location and return it to the runtime.

fn map_mut<T, U>( mut_ref: Self::Mut<T>, f: impl FnOnce(&mut T) -> &mut U ) -> Self::Mut<U>

where U: 'static + ?Sized, T: ?Sized,

Map the mutable ref.

fn map<T, U>(ref_: Self::Ref<T>, f: impl FnOnce(&T) -> &U) -> Self::Ref<U>

where U: 'static + ?Sized, T: ?Sized,

Map the ref.

fn owner() -> Owner<Self>

Create a new owner. The owner will be responsible for dropping all of the generational boxes that it creates.

impl Default for SyncStorage

fn default() -> SyncStorage

Returns the “default value” for a type.

impl<T> Storage<T> for SyncStorage

where T: Sync + Send + 'static,

fn try_read( &'static self, at: GenerationalRefBorrowInfo ) -> Result<<SyncStorage as AnyStorage>::Ref<T>, BorrowError>

Try to read the value. Returns None if the value is no longer valid.

fn try_write( &'static self, at: GenerationalRefMutBorrowInfo ) -> Result<<SyncStorage as AnyStorage>::Mut<T>, BorrowMutError>

Try to write the value. Returns None if the value is no longer valid.

fn set(&self, value: T)

Set the value

fn take(&'static self) -> Option<T>

Take the value out of the storage. This will return the value if the value was taken.
