pub struct FcFontCache { /* private fields */ }

Implementations

impl FcFontCache

pub fn build() -> Self

Builds a new font cache from all fonts discovered on the system

NOTE: Performance-intensive, should only be called on startup!

Examples found in repository

examples/getfont.rs (line 6)

fn main() {
    let start = Instant::now();
    let cache = FcFontCache::build();
    let end = Instant::now();

    let start2 = Instant::now();
    let results = cache.query(&FcPattern {
        name: Some(String::from("Purisa")),
        ..Default::default()
    });
    let end2 = Instant::now();

    println!("built cache in: {:?}", end - start);
    println!("font results: {:?} - queried in {:?}", results, end2 - start2);
}

pub fn list(&self) -> &BTreeMap<FcPattern, FcFontPath>

Returns the list of fonts and font patterns

pub fn query_all(&self, pattern: &FcPattern) -> Vec<&FcFontPath>

Queries a font from the in-memory font -> file mapping, returns all matching fonts

pub fn query(&self, pattern: &FcPattern) -> Option<&FcFontPath>

Queries a font from the in-memory font -> file mapping, returns the first found font (early return)

Trait Implementations

impl Clone for FcFontCache

fn clone(&self) -> FcFontCache

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FcFontCache

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

Formats the value using the given formatter.

impl Default for FcFontCache

fn default() -> FcFontCache

Returns the “default value” for a type.

impl Ord for FcFontCache

fn cmp(&self, other: &FcFontCache) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for FcFontCache

fn eq(&self, other: &FcFontCache) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for FcFontCache

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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