[−][src]Struct rapier2d::data::Coarena
A container for data associated to item existing into another Arena.
Implementations
impl<T> Coarena<T>
[src]
pub fn new() -> Self
[src]
A coarena with no element.
pub fn get(&self, index: Index) -> Option<&T>
[src]
Gets a specific element from the coarena, if it exists.
pub fn get_mut(&mut self, index: Index) -> Option<&mut T>
[src]
Gets a mutable reference to a specific element from the coarena, if it exists.
pub fn ensure_pair_exists(
&mut self,
a: Index,
b: Index,
default: T
) -> (&mut T, &mut T) where
T: Clone,
[src]
&mut self,
a: Index,
b: Index,
default: T
) -> (&mut T, &mut T) where
T: Clone,
Ensure that elements at the two given indices exist in this coarena, and return their reference.
Missing elements are created automatically and initialized with the default
value.
