Struct RunnerRegistry 

pub struct RunnerRegistry { /* private fields */ }

Maps runner names to StepRunner implementations.

Constructed once at startup and shared immutably for the duration of the run.

Implementations

impl RunnerRegistry

pub fn new() -> Self

Create an empty registry.

pub fn register(&mut self, runner: Arc<dyn StepRunner>, is_default: bool)

pub fn resolve(&self, name: Option<&str>) -> Option<Arc<dyn StepRunner>>

Look up a runner by name, falling back to the default when name is None.

pub fn default_runner_name(&self) -> Option<&str>

The name of the current default runner, if one has been set.

pub fn runner_names(&self) -> Vec<&str>

Sorted list of all registered runner names.
