pub struct Coarena<T> { /* private fields */ }
Expand description
A container for data associated to item existing into another Arena.
Implementations
sourceimpl<T> Coarena<T>
impl<T> Coarena<T>
sourcepub fn iter(&self) -> impl Iterator<Item = (Index, &T)>
pub fn iter(&self) -> impl Iterator<Item = (Index, &T)>
Iterates through all the elements of this coarena.
sourcepub 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.
sourcepub fn remove(&mut self, index: Index, removed_value: T) -> Option<T>
pub fn remove(&mut self, index: Index, removed_value: T) -> Option<T>
Deletes an element for the coarena and returns its value.
This method will reset the value to the given removed_value
.
sourcepub fn get(&self, index: Index) -> Option<&T>
pub fn get(&self, index: Index) -> Option<&T>
Gets a specific element from the coarena, if it exists.
sourcepub fn get_mut(&mut self, index: Index) -> Option<&mut T>
pub fn get_mut(&mut self, index: Index) -> Option<&mut T>
Gets a mutable reference to a specific element from the coarena, if it exists.
sourcepub fn insert(&mut self, a: Index, value: T) where
T: Clone + Default,
pub fn insert(&mut self, a: Index, value: T) where
T: Clone + Default,
Inserts an element into this coarena.
sourcepub 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.
