Struct raft::util::Union

pub struct Union<'a> { /* private fields */ }

A convenient struct that handles queries to both HashSet.

Implementations

impl<'a> Union<'a>

pub fn new( first: &'a HashSet<u64, BuildHasherDefault<FxHasher>>, second: &'a HashSet<u64, BuildHasherDefault<FxHasher>> ) -> Union<'a>

Creates a union.

pub fn contains(&self, id: u64) -> bool

Checks if id shows up in either HashSet.

pub fn iter(&self) -> impl Iterator<Item = u64> + '_

Returns an iterator iterates the distinct values in two sets.

pub fn is_empty(&self) -> bool

Checks if union is empty.

pub fn len(&self) -> usize

Gets the count of the union.

The time complexity is O(n).
