Struct Next 

pub struct Next<'a> { /* private fields */ }

Handle passed to each middleware that invokes the rest of the stack.

Held as a slice of the remaining middleware plus a reference to the terminal Worker. Consumed by Next::run so it can’t be called twice from the same middleware invocation.

Implementations

impl<'a> Next<'a>

pub fn run( self, job: &'a Job, ctx: &'a WorkerContext, ) -> Pin<Box<dyn Future<Output = Result<WorkerResult>> + Send + 'a>>

Invoke the next middleware in the stack, or the terminal worker.execute if this is the innermost layer.

Returns a boxed future so the recursion through an unknown-depth middleware stack stays Sized.
