Struct FontAndScriptInfo 

pub(crate) struct FontAndScriptInfo {
    pub font: FontRef,
    pub script: Script,
    pub bidi_level: Level,
    pub language: Language,
    pub letter_spacing: Option<Au>,
    pub word_spacing: Option<Au>,
    pub text_rendering: T,
    pub kerning: T,
}

A data structure which contains information used when shaping a TextRunSegment.

Fields

font: FontRef

The font used when shaping a TextRunSegment.

script: Script

The script used when shaping a TextRunSegment.

bidi_level: Level

The BiDi Level used when shaping a TextRunSegment.

language: Language

The Language used when shaping a TextRunSegment.

letter_spacing: Option<Au>

Spacing to add between each letter. Corresponds to the CSS 2.1 letter-spacing property. NB: You will probably want to set the IGNORE_LIGATURES_SHAPING_FLAG if this is non-null.

Letter spacing is not applied to all characters. Use [Self::letter_spacing_for_character] to determine the amount of spacing to apply.

word_spacing: Option<Au>

Spacing to add between each word. Corresponds to the CSS 2.1 word-spacing property.

text_rendering: T

The TextRendering value from the original style.

kerning: T

The value of the font-kerning property from the original style.

Implementations

impl FontAndScriptInfo

pub(crate) fn simple_for_font(font: FontRef) -> Self

Creates a minimal FontAndScriptInfo for a single font, with generic language settings and the default shaping configuration. This is only used to generate placeholders for text carets on otherwise empty lines.

Trait Implementations

impl Clone for FontAndScriptInfo

fn clone(&self) -> FontAndScriptInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FontAndScriptInfo

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

Formats the value using the given formatter.

impl From<&FontAndScriptInfo> for ShapingOptions

fn from(info: &FontAndScriptInfo) -> Self

Converts to this type from the input type.

impl MallocSizeOf for FontAndScriptInfo

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl PartialEq for FontAndScriptInfo

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