Struct DelegateTextMeasurerFactory 

pub struct DelegateTextMeasurerFactory<F> { /* private fields */ }

Adapter for renderers that already expose a string/font measurement function.

Implementations

impl<F> DelegateTextMeasurerFactory<F>

where F: Fn(&str, &str) -> f64 + 'static,

pub fn new(measure: F) -> DelegateTextMeasurerFactory<F>

Trait Implementations

impl<F> IPretextTextMeasurerFactory for DelegateTextMeasurerFactory<F>

where F: Fn(&str, &str) -> f64 + 'static,

fn name(&self) -> &str

fn create( &self, font: &str, ) -> Result<Rc<dyn IPretextTextMeasurer>, PretextError>

fn is_supported(&self) -> bool

fn priority(&self) -> i32

fn shaper_factory(&self) -> Option<Rc<dyn IPretextTextShaperFactory>>

A combined backend can supply shaping without a second registration.
