Struct ShapedLineCursor 

Source 
pub struct ShapedLineCursor<'a> { /* private fields */ }
Expand description

Incrementally splits a ShapedLine at increasing UTF-8 byte boundaries.

Each piece preserves the original glyphs and decorations, rebased as in ShapedLine::split_at. Byte-ordered glyphs are advanced in linear time, copying each glyph and byte at most once; visually reordered glyphs fall back to the existing split operation.

Implementations§

Source§

impl<'a> ShapedLineCursor<'a>

Source

pub fn take_until(&mut self, byte_index: usize) -> ShapedLine

Takes the bytes since the previous boundary.

Panics if the boundary precedes the previous one, exceeds the line’s length, or falls inside a UTF-8 character.

Source

pub fn x_offset(&self) -> Pixels

Returns the original line’s x position at the current boundary.
