Struct idmap::set::IdSet

pub struct IdSet<T: IntegerId> { /* fields omitted */ }

A set, whose implement IntegerId

This is implemented directly as a bitset, so it may not be appropriate if you know you’ll have large ids but few entries.

Implementations

impl<T: IntegerId> IdSet<T>

pub fn new() -> IdSet<T>

Create a new IdSet

pub fn with_capacity(indexes: usize) -> IdSet<T>

Initialize the set with the given capacity

Since the underlying storage is a simple bitset, this hints at the maximum capacity and not the length

pub fn insert<Q: Borrow<T>>(&mut self, value: Q) -> bool

Inserts the specified element into the set, returning true if it was already in the set and false if it wasn’t.

pub fn remove<Q: Borrow<T>>(&mut self, value: Q) -> bool

Remove the specified value from the set if it is present, returning whether or not it was present.

pub fn contains<Q: Borrow<T>>(&self, value: Q) -> bool

Check if this set contains the specified value

pub fn iter(&self) -> Iter<'_, T>

Iterate over the values in this set

pub fn clear(&mut self)

Clear the values in this set

pub fn len(&self) -> usize

The number of entries in this set

An IdSet internally tracks this length, so this is a O(1) operation

pub fn is_empty(&self) -> bool

If this set is empty

pub fn retain<F: FnMut(&T) -> bool>(&mut self, func: F)

Retain values in the set if the specified closure returns true

Otherwise they are removed
