Struct Task

pub struct Task<'a, Op: Operation, Metadata: Serializable> {
    pub routing_key: String,
    pub metadata: Metadata,
    pub op: &'a Op,
    pub input: Op::Input,
}

Expand description

A Task encodes an Operation paired with arguments.

In addition to the Operation and its arguments, a Task also contains metadata and routing information. The routing information is used to identify the Channel to which execution results should be sent.

Metadata can be any arbitrary Serializable type. It’s typically used by Directives to encode additional information about the computation.

Fields§

§routing_key: String

The routing key used to identify the Channel to which execution results should be sent.

§metadata: Metadata

Metadata associated with the Task.

§op: &'a Op

The Operation to be executed.

§input: Op::Input

The arguments to the Operation.
