Expand description
A container for data associated to item existing into another Arena.
Implementations
impl<T> Coarena<T>
impl<T> Coarena<T>
pub fn get_unknown_gen(&self, index: u32) -> Option<&T>
pub fn get_unknown_gen(&self, index: u32) -> Option<&T>
Gets a specific element from the coarena without specifying its generation number.
It is strongly encouraged to use Coarena::get
instead of this method because this method
can suffer from the ABA problem.
Deletes an element for the coarena and returns its value.
We can’t really remove an element from the coarena. So instead of actually removing
it, this method will reset the value to the given removed_value
.
Gets a specific element from the coarena, if it exists.
Gets a mutable reference to a specific element from the coarena, if it exists.
Inserts an element into this coarena.
pub fn ensure_element_exist(&mut self, a: Index, default: T) -> &mut T where
T: Clone,
pub fn ensure_element_exist(&mut self, a: Index, default: T) -> &mut T where
T: Clone,
Ensure that the given element exists in thihs coarena, and return its mutable reference.

superset. Read more
pub fn is_in_subset(&self) -> bool
pub fn is_in_subset(&self) -> bool
Checks if self
is actually part of its subset T
(and can be converted to it).
pub fn to_subset_unchecked(&self) -> SS
pub fn to_subset_unchecked(&self) -> SS
Use with care! Same as self.to_subset
but without any property checks. Always succeeds.
pub fn from_subset(element: &SS) -> SP
pub fn from_subset(element: &SS) -> SP
The inclusion map: converts self
to the equivalent element of its superset.
