Enum Hinting 

pub enum Hinting {
    Disabled,
    Enabled,
}

Metrics hinting strategy

Variants

Disabled

No metrics hinting.

Glyphs will have subpixel coordinates.

This is the default.

Enabled

Metrics hinting.

Glyphs will be snapped to integral coordinates in the X-axis during layout. This can improve readability for smaller text and/or low-DPI screens.

However, in order to get the right effect, you must use physical coordinates during layout and avoid further scaling when rendering. Otherwise, the rounding errors can accumulate and glyph distances may look erratic.

In other words, metrics hinting makes layouting dependent of the target resolution.

Trait Implementations

impl Clone for Hinting

fn clone(&self) -> Hinting

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Hinting

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

Formats the value using the given formatter.

impl Default for Hinting

fn default() -> Hinting

Returns the “default value” for a type.

impl PartialEq for Hinting

fn eq(&self, other: &Hinting) -> 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.

impl Copy for Hinting

impl Eq for Hinting

impl StructuralPartialEq for Hinting
