Struct FutureQueueContext

pub struct FutureQueueContext { /* private fields */ }

Expand description

Context for a function in a FutureQueue or FutureQueueGrouped.

Implementations§

impl FutureQueueContext

pub fn global_slot(&self) -> u64

Returns a global slot number: an integer that is unique for the lifetime of the future, within the context of the FutureQueue or FutureQueueGrouped it is running in.

The slot number is compact: it starts from 0, and is always the smallest possible number that could be assigned to the future at the moment the function is called.

pub fn group_slot(&self) -> Option<u64>

Returns a group slot number: an integer that is unique for the lifetime of the future within a group.

The slot number is compact: it starts from 0, and is always the smallest possible number that could be assigned to the future at the moment the function is called.

Only set in case FutureQueueGrouped is used, and the future is part of a group.
