Expand description

Built-in GlyphPositioner implementations.

Takes generic LineBreaker to indicate the wrapping style. See BuiltInLineBreaker.

Example

let layout = Layout::default().h_align(HorizontalAlign::Right);

Variants§

§

SingleLine

Fields

§line_breaker: L

Renders a single line from left-to-right according to the inner alignment. Hard breaking will end the line, partially hitting the width bound will end the line.

§

Wrap

Fields

§line_breaker: L

Renders multiple lines from left-to-right according to the inner alignment. Hard breaking characters will cause advancement to another line. A characters hitting the width bound will also cause another line to start.
