Struct FontConfig 

pub struct FontConfig {
    pub default_font: Option<String>,
    pub code_font: Option<String>,
    pub default_font_source: Option<FontSource>,
    pub code_font_source: Option<FontSource>,
    pub fallback_fonts: Vec<String>,
    pub fallback_font_sources: Vec<FontSource>,
    pub enable_subsetting: bool,
}

Configuration for fonts used in the generated PDF.

Both default_font and code_font accept friendly names (“Georgia”, “Helvetica”, “/path/to/font.ttf”) and are resolved at render time. Explicit *_source fields take priority when set.

Fields

default_font: Option<String>

Default font name for body text.

code_font: Option<String>

Font name for code blocks.

default_font_source: Option<FontSource>

Font source for body text. Takes priority over default_font if set.

code_font_source: Option<FontSource>

Font source for code blocks. Takes priority over code_font if set.

fallback_fonts: Vec<String>

Ordered list of fallback font names (system / path / built-in alias). Resolved the same way as default_font at render time. Composed with fallback_font_sources (sources first, then names) and with any fallback_fonts set on [defaults] in the TOML config.

fallback_font_sources: Vec<FontSource>

Ordered list of pre-resolved fallback font sources. Useful when embedding fonts via include_bytes! or pointing at a known path. Composed before fallback_fonts.

enable_subsetting: bool

Enable font subsetting for smaller PDFs.

Implementations

impl FontConfig

pub fn new() -> Self

Create a new FontConfig with default settings.

pub fn with_default_font(self, font: impl Into<String>) -> Self

Set the default body font.

pub fn with_code_font(self, font: impl Into<String>) -> Self
