Trait FormatSelectionProgramExt 

pub trait FormatSelectionProgramExt<This, Predicate>
where
    This: FormatPredicateAlg<Predicate = Predicate> + FormatSelectionAlg<Predicate = Predicate>,
{
    // Required methods
    fn best_progressive_format(&self) -> This::Selection;
    fn preferred_progressive_format(
        &self,
        id: impl Into<String>,
    ) -> This::Selection;
}

Derives common selection programs by equating predicate carriers.

Required Methods

fn best_progressive_format(&self) -> This::Selection

Defines the most preferred progressive format.

fn preferred_progressive_format(&self, id: impl Into<String>) -> This::Selection

Defines an exact format with a progressive fallback.

Dyn Compatibility

This trait is not dyn compatible.

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

Implementors

impl<This, Predicate> FormatSelectionProgramExt<This, Predicate> for This

where This: FormatPredicateAlg<Predicate = Predicate> + FormatSelectionAlg<Predicate = Predicate>,

Derives common selection programs by equating predicate carriers.
