Struct fontconfig::Pattern

#[repr(C)]
pub struct Pattern<'fc> { /* private fields */ }

A safe wrapper around fontconfig’s FcPattern.

Implementations

impl<'fc> Pattern<'fc>

pub fn new(fc: &Fontconfig) -> Pattern<'_>

Create a new empty Pattern.

pub unsafe fn from_pattern(fc: &Fontconfig, pat: *mut FcPattern) -> Pattern<'_>

Create a Pattern from a raw fontconfig FcPattern pointer.

The pattern is referenced.

Safety: The pattern pointer must be valid/non-null.

pub fn add_string(&mut self, name: &CStr, val: &CStr)

Add a key-value pair of type String to this pattern.

See useful keys in the fontconfig reference.

pub fn add_integer(&mut self, name: &CStr, val: c_int)

Add a key-value pair of type Int to this pattern

See useful keys in the fontconfig reference.

pub fn get_string<'a>(&'a self, name: &'a CStr) -> Option<&'a str>

Get string the value for a key from this pattern.

pub fn get_int(&self, name: &CStr) -> Option<i32>

Get the integer value for a key from this pattern.

pub fn print(&self)

Print this pattern to stdout with all its values.

pub fn font_match(&mut self) -> Pattern<'_>

Get the best available match for this pattern, returned as a new pattern.

pub fn name(&self) -> Option<&str>

Get the “fullname” (human-readable name) of this pattern.

pub fn filename(&self) -> Option<&str>

Get the “file” (path on the filesystem) of this font pattern.

pub fn face_index(&self) -> Option<i32>

Get the “index” (The index of the font within the file) of this pattern.

pub fn slant(&self) -> Option<i32>

Get the “slant” (Italic, oblique or roman) of this pattern.

pub fn weight(&self) -> Option<i32>

Get the “weight” (Light, medium, demibold, bold or black) of this pattern.

pub fn width(&self) -> Option<i32>

Get the “width” (Condensed, normal or expanded) of this pattern.

pub fn format(&self) -> Result<FontFormat, UnknownFontFormat>

Get the “fontformat” (“TrueType” “Type 1” “BDF” “PCF” “Type 42” “CID Type 1” “CFF” “PFR” “Windows FNT”) of this pattern.

pub fn as_ptr(&self) -> *const FcPattern

Returns a raw pointer to underlying FcPattern.

pub fn as_mut_ptr(&mut self) -> *mut FcPattern

Returns an unsafe mutable pointer to the underlying FcPattern.

impl Pattern<'_>

pub fn lang_set(&self) -> Option<StrList<'_>>

Get the languages set of this pattern.
