Enum PayloadKind

Source 
pub enum PayloadKind {
    Earliest,
    WaitForPending,
}
Expand description

Determines how we should choose the payload to return.

Variants§

§

Earliest

Returns the next best available payload (the earliest available payload). This does not wait for a real for pending job to finish if there’s no best payload yet and is allowed to race various payload jobs (empty, pending best) against each other and returns whichever job finishes faster.

This should be used when it’s more important to return a valid payload as fast as possible. For example, the engine API timeout for engine_getPayload is 1s and clients should rather return an empty payload than indefinitely waiting for the pending payload job to finish and risk missing the deadline.

§

WaitForPending

Only returns once we have at least one built payload.

Compared to PayloadKind::Earliest this does not race an empty payload job against the already in progress one, and returns the best available built payload or awaits the job in progress.
