Struct glyph_brush::GlyphCalculatorBuilder

source · [−]

pub struct GlyphCalculatorBuilder<F = FontArc, H = DefaultSectionHasher> { /* private fields */ }

Expand description

Builder for a GlyphCalculator.

Example

use glyph_brush::{ab_glyph::FontArc, GlyphCalculator, GlyphCalculatorBuilder};

let dejavu = FontArc::try_from_slice(include_bytes!("../../fonts/DejaVuSans.ttf")).unwrap();
let mut glyphs: GlyphCalculator = GlyphCalculatorBuilder::using_font(dejavu).build();

Implementations

impl<F: Font> GlyphCalculatorBuilder<F>

pub fn using_font(font: F) -> Self

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

pub fn using_fonts(fonts: Vec<F>) -> Self

impl<F: Font, H: BuildHasher> GlyphCalculatorBuilder<F, H>

pub fn add_font<I: Into<F>>(&mut self, font_data: I) -> FontId

Adds additional fonts to the one added in using_font.

Returns a FontId to reference this font.

pub fn section_hasher<T: BuildHasher>(
self,
section_hasher: T
) -> GlyphCalculatorBuilder<F, T>

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<X>(self) -> GlyphCalculator<F, X, H>

Builds a GlyphCalculator
