Struct ListSet

Source

pub struct ListSet<S>(/* private fields */);

Expand description

A set backed by a mutable slice-like data structure.

This data structure uses two different strategies depending on size:

When the list is small, it is just kept as is and searched linearly in contains.
When the list is a bit bigger, it’s sorted in new and then binary-searched for containment checks.

Implementations§

Source §

impl<T, S> ListSet<S>
where S: DerefMut<Target = [T]>, T: Ord,

Source

pub fn new(list: S) -> Self

Creates a new list set.

If the list is longer than the cutoff point, it is sorted.

Source

pub fn is_empty(&self) -> bool

Whether the set contains no elements.

Source

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

Checks whether the set contains the given value.

If the list is shorter than the cutoff point, performs a linear search. If it is longer, performs a binary search.
