Implementations

impl IndexSet

pub fn new() -> IndexSet

Create a new, empty set.

pub fn clear(&mut self)

Clear the set.

pub fn union_one_range(&mut self, start: usize, end: usize)

Add the range start..end to the set.

pub fn delete_range(&mut self, start: usize, end: usize)

Deletes the given range from the set.

pub fn minus_one_range(&self, start: usize, end: usize) -> MinusIter<'_>

Return an iterator that yields start..end minus the coverage in this set.

pub fn apply_delta(&self, delta: &RopeDelta) -> IndexSet

Computes a new set based on applying a delta to the old set. Collapsed regions are removed and contiguous regions are combined.
