[−][src]Macro stakker::timer_max

macro_rules! timer_max {
    ( $var:expr, $inst:expr, $($x:tt)+ ) => { ... };
}

Create or update a "Max" timer

A "Max" timer expires at the latest (greatest) expiry time provided. Modifies a MaxTimerKey variable or structure member provided by the caller, which should be initialised with Default::default() (which is an invalid timer key). If the timer key currently in the variable is invalid or expired, then a new timer is created using the call-args following, and the key stored in the variable. Otherwise the timer expiry time is updated with the maximum of the current and provided expiry times, and the call-args are ignored. The timer may be deleted using Core::timer_max_del.

The syntax of the calls is identical to call!, but with a variable reference and Instant argument first. However the plain [actor], ... form is not accepted because a Core reference is always needed.

ⓘThis example is not tested
let mut var = Default::default();
  :::
timer_max!(&mut var, instant, ...args-as-for-call-macro...);

Implemented using Core::timer_max_upd, Core::timer_max_add, Actor::apply and Actor::apply_prep.
