Implementations§

Source§

impl<T: Eq + Hash + 'static> Set<T>

Source

pub fn try_new() -> Result<Self, SetError>

Source

pub fn try_insert(&mut self, value: T) -> Result<SetId<T>, SetError>

Source

pub fn len(&self) -> usize

Source

pub fn is_empty(&self) -> bool

Source

pub fn capacity(&self) -> usize

Source

pub fn find(&self, value: &T) -> Option<SetId<T>>

Returns the SetId for value if it exists in the set, without inserting.

This is primarily intended for tests and debugging. In typical usage you should prefer try_insert which handles both existence checks and insertion atomically in the intended access pattern.

Source

pub unsafe fn get(&self, id: SetId<T>) -> &T

Returns a shared reference to the value for a given SetId.

§Safety
  • The id must have been obtained from this exact Set<T> instance (or remain valid for it). Using an id from another set, or after the backing arena is torn down, is undefined behavior.
§Safety
  • id must have been obtained from this exact Set<T> instance and still refer to a live element in its arena.
