[−][src]Struct tiny_ecs::MapRef
Immutable reference container for Persist
returned by Entities::borrow()
This struct is required to contain a hidden borrow to the requested Persist
.
The reason for this is so we can borrow multiple Persist
, but not break the
borrow checker rules for borrows on a single Persist
.
Methods from Deref<Target = Persist<T>>
pub fn len(&self) -> usize
[src]
Returns the actual used length regardless of capacity
pub fn is_empty(&self) -> bool
[src]
pub fn capacity(&self) -> usize
[src]
Returns the storage capacity
pub fn get(&self, index: usize) -> Option<&T>
[src]
pub fn is_index_live(&self, index: usize) -> bool
[src]
Check if there is a value at this index
pub fn iter(&self) -> Iter<T>
[src]
