Struct wgpu_core::storage::Storage

source ·
pub(crate) struct Storage<T>
where T: StorageItem,
{ pub(crate) map: Vec<Element<T>>, kind: &'static str, }
Expand description

A table of T values indexed by the id type I.

Storage implements std::ops::Index, accepting Id values as indices.

The table is represented as a vector indexed by the ids’ index values, so you should use an id allocator like IdentityManager that keeps the index values dense and close to zero.
