Struct glyph_brush::GlyphCalculatorBuilder

pub struct GlyphCalculatorBuilder<'a, H = RandomXxHashBuilder64> { /* fields omitted */ }

Builder for a GlyphCalculator.

Example

use glyph_brush::GlyphCalculatorBuilder;

let dejavu: &[u8] = include_bytes!("../../fonts/DejaVuSans.ttf");
let mut glyphs = GlyphCalculatorBuilder::using_font_bytes(dejavu).build();

Methods

impl<'a> GlyphCalculatorBuilder<'a, RandomXxHashBuilder64>

pub fn using_font_bytes<B>(
    font_0_data: B
) -> GlyphCalculatorBuilder<'a, RandomXxHashBuilder64> where
    B: Into<SharedBytes<'a>>, 

Specifies the default font data used to render glyphs. Referenced with FontId(0), which is default.

pub fn using_fonts_bytes<B, V>(
    font_data: V
) -> GlyphCalculatorBuilder<'a, RandomXxHashBuilder64> where
    B: Into<SharedBytes<'a>>,
    V: Into<Vec<B>>, 

pub fn using_font(
    font_0_data: Font<'a>
) -> GlyphCalculatorBuilder<'a, RandomXxHashBuilder64>

Specifies the default font used to render glyphs. Referenced with FontId(0), which is default.

pub fn using_fonts<V>(
    fonts: V
) -> GlyphCalculatorBuilder<'a, RandomXxHashBuilder64> where
    V: Into<Vec<Font<'a>>>, 

impl<'a, H> GlyphCalculatorBuilder<'a, H> where
    H: BuildHasher, 

pub fn add_font_bytes<B>(&mut self, font_data: B) -> FontId where
    B: Into<SharedBytes<'a>>, 

Adds additional fonts to the one added in using_font / using_font_bytes.

Returns a FontId to reference this font.

pub fn add_font(&mut self, font_data: Font<'a>) -> FontId

Adds additional fonts to the one added in using_font / using_font_bytes.

Returns a FontId to reference this font.

pub fn section_hasher<T>(
    self,
    section_hasher: T
) -> GlyphCalculatorBuilder<'a, T> where
    T: BuildHasher, 

Sets the section hasher. GlyphCalculator cannot handle absolute section hash collisions so use a good hash algorithm.

This hasher is used to distinguish sections, rather than for hashmap internal use.

Defaults to xxHash.

pub fn build(self) -> GlyphCalculator<'a, H>

Builds a GlyphCalculator

Trait Implementations

    H: Clone, 

fn clone(&self) -> GlyphCalculatorBuilder<'a, H>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, H> Debug for GlyphCalculatorBuilder<'a, H> where
