Enum gfx_glyph::Layout

pub enum Layout<G: GlyphGrouper> {
    SingleLine(G, HorizontalAlign),
    Wrap(G, HorizontalAlign),
}

Built-in GlyphPositioner implementations.

Takes generic GlyphGrouper to indicate the wrapping style, see GlyphGroup for built-in groupings.

Variants

SingleLine(G, HorizontalAlign)

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

Wrap(G, HorizontalAlign)

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

Methods

impl<G: GlyphGrouper> Layout<G>

fn calculate_glyphs_and_leftover<'a>(
    &self,
    font: &Font,
    section: &GlyphInfo<'a>
) -> (Vec<PositionedGlyph>, Option<LayoutLeftover<'a>>)

Trait Implementations

impl<G: Debug + GlyphGrouper> Debug for Layout<G>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<G: Clone + GlyphGrouper> Clone for Layout<G>

fn clone(&self) -> Layout<G>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<G: Copy + GlyphGrouper> Copy for Layout<G>

impl<G: Hash + GlyphGrouper> Hash for Layout<G>

fn hash<__HG: Hasher>(&self, __arg_0: &mut __HG)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].

impl Default for Layout<GlyphGroup>

fn default() -> Self

Returns the "default value" for a type.

impl<Grouper: GlyphGrouper> GlyphPositioner for Layout<Grouper>

fn calculate_glyphs<'a, G: Into<GlyphInfo<'a>>>(
    &self,
    font: &Font,
    section: G
) -> Vec<PositionedGlyph>

Calculate a sequence of positioned glyphs to render. Custom implementations should always return the same result when called with the same arguments. If not consider disabling cache_glyph_positioning.

fn bounds_rect<'a, G: Into<GlyphInfo<'a>>>(&self, section: G) -> Rect<f32>

Return a rectangle according to the requested render position and bounds appropriate for the glyph layout.
