Implementations

impl<'a, Font: AbstractFont> TextParagraphLayout<'a, Font>

pub fn layout_lines<R>( &self, line_callback: impl FnMut(&mut dyn Iterator<Item = PositionedGlyph<Font::Length>>, Font::Length, Font::Length, &TextLine<Font::Length>, Option<Range<Font::Length>>) -> ControlFlow<R>, selection: Option<Range<usize>>, ) -> Result<Font::Length, R>

Layout the given string in lines, and call the layout_line callback with the line to draw at position y. The signature of the layout_line function is: (glyph_iterator, line_x, line_y, text_line, selection). Returns the baseline y coordinate as Ok, or the break value if line_callback returns core::ops::ControlFlow::Break.

pub fn cursor_pos_for_byte_offset( &self, byte_offset: usize, ) -> (Font::Length, Font::Length)

Returns the leading edge of the glyph at the given byte offset

pub fn byte_offset_for_position( &self, (pos_x, pos_y): (Font::Length, Font::Length), ) -> usize

Returns the bytes offset for the given position
