Enum glow_glyph::Layout [−]
pub enum Layout<L> where
L: LineBreaker, {
SingleLine {
line_breaker: L,
h_align: HorizontalAlign,
v_align: VerticalAlign,
},
Wrap {
line_breaker: L,
h_align: HorizontalAlign,

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
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
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.
