Struct webrender::intern::DataStore

pub struct DataStore<I: Internable> {
    items: Vec<Option<I::StoreData>>,
}

The data store lives in the frame builder thread. It contains a free-list of items for fast access.

Fields

items: Vec<Option<I::StoreData>>

Implementations

impl<I: Internable> DataStore<I>

pub fn apply_updates( &mut self, update_list: UpdateList<I::Key>, profile: &mut TransactionProfile, )

Apply any updates from the scene builder thread to this data store.

fn default() -> Self

Returns the “default value” for a type.

impl<I: Internable> Index<Handle<I>> for DataStore<I>

Retrieve an item from the store via handle

type Output = <I as Internable>::StoreData

The returned type after indexing.

fn index(&self, handle: Handle<I>) -> &I::StoreData

Performs the indexing (container[index]) operation.

impl<I> MallocSizeOf for DataStore<I>

where I: MallocSizeOf + Internable,

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize
