Expand description

Read-only sequence facts for analysis and editors.

Required Methods§

Source

fn step_count(&mut self, sequence: SequenceRef) -> Option<usize>

Returns the step count, or None if the sequence is missing.

Source

fn step_facts( &mut self, sequence: SequenceRef, index: usize, ) -> Option<StepFacts>

Returns one step’s facts, or None if the sequence or step is missing.

Provided Methods§

Source

fn step_enabled(&mut self, sequence: SequenceRef, index: usize) -> Option<bool>

Returns whether one step is enabled, or None if it is missing.

The default implementation derives the answer from Self::step_facts.

Source

fn name(&mut self, sequence: SequenceRef) -> String

Returns a display name.

Dyn Compatibility§

This trait is dyn compatible.

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