Trait FontRefExt 

pub trait FontRefExt {
    // Required methods
    fn get_bytes(&self) -> &[u8] ;
    fn get_full_font_metrics(&self) -> FontMetrics;
}

Extension trait for FontRef to provide access to font bytes and metrics

This trait provides methods that require access to the inner ParsedFont data.

Required Methods

fn get_bytes(&self) -> &[u8]

Get the original font bytes. Returns an empty slice when the underlying ParsedFont was created without retaining its source bytes (the default since the lazy-font-loading refactor). Callers that need the bytes for PDF embedding must construct the ParsedFont via ParsedFont::with_source_bytes.

fn get_full_font_metrics(&self) -> FontMetrics

Get the full font metrics (PDF-style metrics from HEAD, HHEA, OS/2 tables)

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
