Struct generational_box::UnsyncStorage

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

A unsync storage. This is the default storage type.

Trait Implementations

impl AnyStorage for UnsyncStorage

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

The reference this storage type returns.

type Mut<'a, W: ?Sized + 'static> = GenerationalRefMut<RefMut<'a, W>>

The mutable reference this storage type returns.

fn downcast_lifetime_ref<'a: 'b, 'b, T: ?Sized + 'static>( ref_: Self::Ref<'a, T> ) -> Self::Ref<'b, T>

Downcast a reference in a Ref to a more specific lifetime

fn downcast_lifetime_mut<'a: 'b, 'b, T: ?Sized + 'static>( mut_: Self::Mut<'a, T> ) -> Self::Mut<'b, T>

Downcast a mutable reference in a RefMut to a more specific lifetime

fn try_map<I: ?Sized + 'static, U: ?Sized + 'static>( _self: Self::Ref<'_, I>, f: impl FnOnce(&I) -> Option<&U> ) -> Option<Self::Ref<'_, U>>

Try to map the ref.

fn try_map_mut<I: ?Sized + 'static, U: ?Sized + 'static>( mut_ref: Self::Mut<'_, I>, f: impl FnOnce(&mut I) -> Option<&mut U> ) -> Option<Self::Mut<'_, U>>

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<Self>

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

fn recycle(location: &MemoryLocation<Self>)

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

fn map_mut<T: ?Sized + 'static, U: ?Sized + 'static>( mut_ref: Self::Mut<'_, T>, f: impl FnOnce(&mut T) -> &mut U ) -> Self::Mut<'_, U>

Map the mutable ref.

fn map<T: ?Sized, U: ?Sized + 'static>( ref_: Self::Ref<'_, T>, f: impl FnOnce(&T) -> &U ) -> Self::Ref<'_, U>

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 UnsyncStorage

fn default() -> UnsyncStorage

Returns the “default value” for a type.

impl<T: 'static> Storage<T> for UnsyncStorage

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

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 Returns None if the value is no longer valid.

fn try_write( &'static self, at: GenerationalRefMutBorrowInfo ) -> Result<Self::Mut<'static, 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.
