Struct SpacePenalty 

pub struct SpacePenalty {
    pub excessive_stretch: u64,
    pub excessive_shrink: u64,
    pub tracking_penalty: u64,
}

Penalty modifiers for space adjustment quality.

Higher values make the optimizer work harder to avoid that adjustment.

Fields

excessive_stretch: u64

Extra demerit for stretching beyond 75% of max stretch.

excessive_shrink: u64

Extra demerit for shrinking beyond 75% of max shrink.

tracking_penalty: u64

Extra demerit for any inter-character spacing adjustment.

Implementations

impl SpacePenalty

pub const DEFAULT: Self

Default penalties: moderate discouragement of extreme adjustments.

pub const PERMISSIVE: Self

Permissive: allow aggressive adjustments with low penalty.

pub const STRICT: Self

Strict: strongly discourage any visible adjustment.

pub fn evaluate(&self, ratio_fixed: i32, category: SpaceCategory) -> u64

Evaluate the penalty for a given adjustment ratio and space category.

ratio_fixed is in 1/256ths (positive = stretch, negative = shrink). Returns additional demerits beyond the base badness.

Trait Implementations

impl Clone for SpacePenalty

fn clone(&self) -> SpacePenalty

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SpacePenalty

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

Formats the value using the given formatter.

impl Default for SpacePenalty

fn default() -> Self

Returns the “default value” for a type.

impl Hash for SpacePenalty

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SpacePenalty

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