Struct ScriptRequirement 

pub struct ScriptRequirement { /* private fields */ }

One resolved script requirement: an OpenType tag group plus an optional Unicode script. Built by resolve_scripts.

Implementations

impl ScriptRequirement

pub fn input(&self) -> &str

The original input tag string.

pub fn ot_tags(&self) -> &[Tag]

The OpenType tag group; any one present in the font satisfies the OT path.

pub fn unicode_script(&self) -> Option<Script>

The Unicode script the font’s cmap must cover, if any.

pub fn ot_satisfied(&self, font_scripts: &HashSet<Tag>) -> bool

Whether the font’s GSUB/GPOS script tags satisfy the OpenType path.

pub fn unicode_satisfied<I>(&self, codepoints: I) -> bool

where I: IntoIterator<Item = char>,

Whether the given codepoints cover this requirement’s Unicode script.

Returns false when the input mapped to no Unicode script. Otherwise, counts codepoints belonging to that script and stops early once MIN_UNICODE_COVERAGE is reached.
