Represents the Task Execution Service (TES) backend.

Implementations

impl TesBackend

pub async fn new(task: &TaskConfig, config: &TesBackendConfig) -> Result<Self>

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

Trait Implementations

impl TaskExecutionBackend for TesBackend

fn max_concurrency(&self) -> u64

Gets the maximum concurrent tasks supported by the backend.

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