Struct BasicTask 

pub struct BasicTask { /* private fields */ }

A task whose body is an async closure.

This is the workhorse for ad-hoc workflows and tests:

use dag_executor::tasks::BasicTask;
let t = BasicTask::new("greet", |_ctx| async { Ok(serde_json::json!("hi")) })
    .with_deps(["setup"])
    .with_priority(10);

Implementations

impl BasicTask

pub fn new<F, Fut>(id: impl Into<String>, f: F) -> Self

where F: Fn(Arc<Context>) -> Fut + Send + Sync + 'static, Fut: Future<Output = Result<TaskOutput, TaskError>> + Send + 'static,

Create a task with id id running async closure f.

pub fn with_deps<I, S>(self, deps: I) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

Declare the tasks this one depends on.

pub fn with_priority(self, priority: u8) -> Self

Set the scheduling priority (higher runs first).

Trait Implementations

impl Task for BasicTask

fn id(&self) -> &str

Stable, unique identifier for this task within a DAG.

fn dependencies(&self) -> Vec<String>

Ids of tasks that must complete successfully before this one runs.

fn priority(&self) -> u8

Scheduling priority; higher values are scheduled first among ready tasks.

fn execute<'life0, 'async_trait>( &'life0 self, ctx: Arc<Context>, ) -> Pin<Box<dyn Future<Output = Result<TaskOutput, TaskError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Execute the task.
