Struct shine_ecs::resources::named::WriteGuard

pub struct WriteGuard<'a, D> where
    D: Data + 'a,  { /* fields omitted */ }

Guarded update access to a store

Methods

impl<'a, D> WriteGuard<'a, D> where
    D: 'a + Data, 

pub fn get(&self, k: &<D as Data>::Key) -> Option<Index<D>>

pub fn get_or_add(&mut self, k: &<D as Data>::Key) -> Index<D>

pub fn is_empty(&self) -> bool

Returns if the store is empty.

pub fn finalize_requests(&mut self)

Move all new (pending) resources into the active resources

pub fn drain_unused_filtered<F>(&mut self, filter: F) where
    F: FnMut(&mut D) -> bool, 

Drain unreferenced elements those specified by the predicate. In other words, remove all unreferenced resources such that f(&mut data) returns true.

pub fn drain_unused(&mut self)

Drain all unreferenced items. Only the referenced items are kept in the store.

pub fn at(&self, index: &Index<D>) -> &D

pub fn at_mut(&mut self, index: &Index<D>) -> &mut D

fn index(
    &self,
    index: &Index<D>
) -> &<WriteGuard<'a, D> as Index<&'i Index<D>>>::Output

Performs the indexing (container[index]) operation.
