Struct Storage

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

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

Storage implements core::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.

Fields

map: Vec<Element<T>>

kind: &'static str

Implementations

impl<T> Storage<T>

where T: StorageItem,

pub(crate) fn new() -> Self

impl<T> Storage<T>

where T: StorageItem,

pub(crate) fn insert(&mut self, id: Id<T::Marker>, value: T)

pub(crate) fn remove(&mut self, id: Id<T::Marker>) -> T

pub(crate) fn iter(&self) -> impl Iterator<Item = (Id<T::Marker>, &T)>

impl<T> Storage<T>

where T: StorageItem + Clone,

pub(crate) fn get(&self, id: Id<T::Marker>) -> T

Get an owned reference to an item. Panics if there is an epoch mismatch, the entry is empty or in error.
