Struct Set 

pub struct Set<T: Hash + Eq + 'static> { /* private fields */ }

Implementations

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

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

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

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn capacity(&self) -> usize

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.

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.

Trait Implementations

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

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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

fn drop(&mut self)

Executes the destructor for this type.
