Enum Node 

pub enum Node {
    Deterministic(Box<dyn for<'a> Fn(&'a mut World) -> BoxFuture<'a, Result<NodeOutput, HarnessError>> + Send + Sync>),
    Agent(Box<dyn for<'a> Fn(&'a mut World) -> BoxFuture<'a, Result<NodeOutput, HarnessError>> + Send + Sync>),
}

One executable node.

Variants

Deterministic(Box<dyn for<'a> Fn(&'a mut World) -> BoxFuture<'a, Result<NodeOutput, HarnessError>> + Send + Sync>)

Deterministic Rust closure. Receives &mut World. Cheap; no tokens.

Agent(Box<dyn for<'a> Fn(&'a mut World) -> BoxFuture<'a, Result<NodeOutput, HarnessError>> + Send + Sync>)

User-supplied async closure that knows how to run an agent loop. Receives &mut World. This is the v0.1 escape hatch.

Implementations

impl Node

pub fn deterministic<F>(f: F) -> Self

where F: for<'a> Fn(&'a mut World) -> BoxFuture<'a, Result<NodeOutput, HarnessError>> + Send + Sync + 'static,

Wrap a closure that returns a boxed future. The closure body can borrow &mut World for the future’s lifetime.

Node::deterministic(|w| Box::pin(async move {
    let out = w.runner.exec("git", &["status"], None).await?;
    Ok(NodeOutput { transition: Transition::Next, data: ... })
}))

pub fn agent<F>(f: F) -> Self

where F: for<'a> Fn(&'a mut World) -> BoxFuture<'a, Result<NodeOutput, HarnessError>> + Send + Sync + 'static,
