Enum ShaperMode

pub(crate) enum ShaperMode {
    Nominal,
    BestEffort,
}

Determines the fidelity with which we apply shaping in the autohinter.

Shaping only affects glyph style classification and the glyphs that are chosen for metrics computations. We keep the Nominal mode around to enable validation of internal algorithms against a configuration that is known to match FreeType. The BestEffort mode should always be used for actual rendering.

Variants

Nominal

Characters are mapped to nominal glyph identifiers and layout tables are not used for style coverage.

This matches FreeType when HarfBuzz support is not enabled.

BestEffort

Simple substitutions are applied according to script rules and layout tables are used to extend style coverage beyond the character map.

Trait Implementations

impl Clone for ShaperMode

fn clone(&self) -> ShaperMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShaperMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ShaperMode

fn eq(&self, other: &ShaperMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
