Derives named and comparative predicates from primitive observation construction.

Required Methods

fn has_audio(&self) -> This::Predicate

Defines formats containing audio.

fn has_video(&self) -> This::Predicate

Defines formats containing video.

fn format_extension(&self, extension: impl Into<String>) -> This::Predicate

Defines formats stating one container or filename extension.

fn at_most(&self, key: impl Into<String>, value: f64) -> This::Predicate

Defines formats whose observation is no greater than the stated number.

fn at_least(&self, key: impl Into<String>, value: f64) -> This::Predicate

Defines formats whose observation is no smaller than the stated number.

fn exactly(&self, key: impl Into<String>, value: f64) -> This::Predicate

Defines formats whose observation equals the stated number.

fn less_than(&self, key: impl Into<String>, value: f64) -> This::Predicate

Defines formats whose observation is smaller than the stated number.

fn greater_than(&self, key: impl Into<String>, value: f64) -> This::Predicate

Defines formats whose observation is greater than the stated number.

fn progressive_format(&self) -> This::Predicate

Defines formats containing both audio and video.

fn audio_only_format(&self) -> This::Predicate

Defines formats containing audio and no video.

fn video_only_format(&self) -> This::Predicate

Defines formats containing video and no audio.

Dyn Compatibility

This trait is not dyn compatible.

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