Implementations

impl<'a> Shaper<'a>

pub(crate) fn from_font(font: &'a FontInstance) -> Option<Self>

pub fn units_per_em(&self) -> i32

Returns font’s units per EM.

pub fn coords(&self) -> &'a [NormalizedCoord]

Returns the currently active normalized coordinates.

pub fn shape( &self, buffer: UnicodeBuffer, options: ShapeOptions<'_>, ) -> GlyphBuffer

Shapes the buffer content using provided options.

Consumes the buffer. You can then run GlyphBuffer::clear to get the UnicodeBuffer back without allocating a new one.

If a plan is provided, it is up to the caller to ensure that the shape plan matches the properties of the provided buffer, otherwise the shaping result will likely be incorrect.

Panics

Will panic when debugging assertions are enabled if the buffer and plan have mismatched properties.

fn shape_with_plan( &self, plan: &ShapePlan, buffer: UnicodeBuffer, options: ShapeOptions<'_>, ) -> GlyphBuffer

pub(crate) fn glyph_names(&self) -> GlyphNames<'a>

pub(crate) fn glyph_metrics(&self) -> GlyphMetrics<'a>

pub(crate) fn layout_table( &self, table_index: TableIndex, ) -> Option<LayoutTable<'a>>

pub(crate) fn layout_tables( &self, ) -> impl Iterator<Item = (TableIndex, LayoutTable<'a>)> + '_
