Struct oatie::stepper::charcursor::CharCursor

pub struct CharCursor<S: Schema> { /* fields omitted */ }

Indexes into a DocString, tracking two owned DocStrings left() and right() which can be retrieved by reference. Because indexing into the string is performed on DocString internals, this makes scanning a Unicode string much faster than split_at().

This method tests for !=.

impl<S: Clone + Schema> Clone for CharCursor<S>

fn clone(&self) -> CharCursor<S>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<S: Debug + Schema> Debug for CharCursor<S>

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
