Struct FontConfig 

pub struct FontConfig {
    pub size: f32,
    pub aliases: BTreeMap<String, FontAliases>,
    pub fonts: BTreeMap<TextClass, FontSelector<'static>>,
    pub raster: RasterConfig,
}

Font configuration

Note that only changes to Self::size are currently supported at run-time.

Fields

size: f32

Standard font size, in units of pixels-per-Em

aliases: BTreeMap<String, FontAliases>

Font aliases, used when searching for a font family matching the key.

Example:

aliases:
  sans-serif:
    mode: Prepend
    list:
    - noto sans

Fonts are named by family. Several standard families exist, e.g. “serif”, “sans-serif”, “monospace”; these resolve to a list of aliases (e.g. “Noto Sans”, “DejaVu Sans”, “Arial”), each of which may have further aliases.

In the above example, “noto sans” is inserted at the top of the alias list for “sans-serif”.

Supported modes: Prepend, Append, Replace.

fonts: BTreeMap<TextClass, FontSelector<'static>>

Standard fonts

raster: RasterConfig

Text glyph rastering settings

Implementations

impl FontConfig

Getters

pub fn size(&self) -> f32

Standard font size

Units: logical (unscaled) pixels per Em.

To convert to Points, multiply by three quarters.

pub fn iter_fonts( &self, ) -> impl Iterator<Item = (&TextClass, &FontSelector<'static>)>

Get an iterator over font mappings

impl FontConfig

Setters

pub fn set_size(&mut self, pt_size: f32) -> Action

Set standard font size

Units: logical (unscaled) pixels per Em.

To convert to Points, multiply by three quarters.

impl FontConfig

Other functions

pub fn raster(&self) -> &RasterConfig

Get raster config

Trait Implementations

impl Clone for FontConfig

fn clone(&self) -> FontConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FontConfig

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

Formats the value using the given formatter.

impl Default for FontConfig

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FontConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for FontConfig

fn eq(&self, other: &FontConfig) -> 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 Serialize for FontConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
