Struct Claimant 

pub struct Claimant { /* private fields */ }

A holder’s handle on one slot of a Budget: what a divisible entry hands the worker. Copy, so a worker may keep one per loop it runs.

Implementations

impl Claimant

pub fn want(&self, units: u32)

State this slot’s demand.

pub fn release(&self)

Give the share back early. The supervisor does this when the holder stops; a holder that is done with the budget mid-run does it itself.

pub fn grant(&self) -> u32

This slot’s current grant.

pub async fn wait_grant_change(&self, seen: u32) -> u32

Wait until the grant differs from seen, then return it. Uses a check/register/recheck to avoid missing a rebalance between the load and the park. Only one waiter may park per slot; use your own Claimant.

pub const fn slot(&self) -> u8

The slot this handle is bound to.
