Type Alias VariationSetting

pub type VariationSetting = Setting<f32>;

Type for specifying a variation axis setting in user coordinates.

The selector field should contain a tag that corresponds to a variation axis while the value field specifies the desired position on the axis in user coordinates (i.e. within the range defined by the minimum and maximum values of the axis).

Example

use skrifa::{Tag, setting::VariationSetting};

// For convenience, a conversion from (&str, f32) is provided.
let slightly_bolder: VariationSetting = ("wght", 720.0).into();

assert_eq!(slightly_bolder, VariationSetting::new(Tag::new(b"wght"), 720.0));

Aliased Type

struct VariationSetting {
    pub selector: Tag,
    pub value: f32,
}

Fields

selector: Tag

Tag that specifies the target setting.

value: f32

The desired value for the setting.

Implementations

impl<T> Setting<T>

pub fn new(selector: Tag, value: T) -> Self

Creates a new setting from the given selector tag and its associated value.

Trait Implementations

impl<T: Clone> Clone for Setting<T>

fn clone(&self) -> Setting<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Setting<T>

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

Formats the value using the given formatter.

impl<T: Copy> From<&(&str, T)> for Setting<T>

fn from(s: &(&str, T)) -> Self

Converts to this type from the input type.

impl<T: Copy> From<&(Tag, T)> for Setting<T>

fn from(s: &(Tag, T)) -> Self

Converts to this type from the input type.

impl<T: Copy> From<&Setting<T>> for Setting<T>

fn from(value: &Setting<T>) -> Self

Converts to this type from the input type.

impl<T> From<(&str, T)> for Setting<T>

fn from(s: (&str, T)) -> Self

Converts to this type from the input type.

impl<T> From<(Tag, T)> for Setting<T>

fn from(s: (Tag, T)) -> Self

Converts to this type from the input type.

impl<T: Ord> Ord for Setting<T>

fn cmp(&self, other: &Setting<T>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<T: PartialEq> PartialEq for Setting<T>

fn eq(&self, other: &Setting<T>) -> 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<T: PartialOrd> PartialOrd for Setting<T>

fn partial_cmp(&self, other: &Setting<T>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
