Struct LocalBackend 

pub struct LocalBackend { /* private fields */ }

Represents a task execution backend that locally executes tasks.

Warning: the local task execution backend spawns processes on the host directly without the use of a container; only use this backend on trusted WDL.

Implementations

impl LocalBackend

pub fn new( config: Arc<Config>, backend_config: &LocalBackendConfig, events: Option<Sender<Event>>, ) -> Result<Self>

Constructs a new local task execution backend with the given configuration.

The provided configuration is expected to have already been validated.

fn constraints( &self, requirements: &HashMap<String, Value>, _: &HashMap<String, Value>, ) -> Result<TaskExecutionConstraints>

Gets the execution constraints given a task’s requirements and hints.

fn guest_inputs_dir(&self) -> Option<&'static str>

Gets the guest (container) inputs directory of the backend.

fn needs_local_inputs(&self) -> bool
