Enum MutGuard 

pub enum MutGuard<'a> {
    Raw(&'a mut Index),
    RefCell(RefMut<'a, Index>),
}

A mutable index guard returned by IndexRef::get_mut.

This type abstracts over either a plain mutable reference or a mutable RefCell borrow.

Variants

Raw(&'a mut Index)

RefCell(RefMut<'a, Index>)

Methods from Deref<Target = Index>

pub fn count(&self) -> usize

length of index The API has guaranteed that self.line_offsets.len() > 0

pub fn end(&self) -> Option<Offset>

ending offset of the source

pub fn query(&self) -> Query<'_>

Get the query and freeze index when querying

pub fn get_line_offset_mut(&mut self, line_no: usize) -> Option<&mut Offset>

pub fn add_next_line(&mut self, offset: Offset)

Add next line offset to index

pub fn clear(&mut self)

Reset the index
