Struct rotor::EarlyScope
[−]
[src]
pub struct EarlyScope<'a> { /* fields omitted */ }
This is a structure that works similarly to Scope, but doesn't have a context
The primary (and probably the only) use case for the EarlyScope
is to
allow to create a state machine before context has been intialized. This
is useful if you want to put a Notifier
of the FSM to a context itself.
Methods
impl<'a> EarlyScope<'a>
[src]
fn register(&mut self, io: &Evented, interest: EventSet, opt: PollOpt) -> Result<()>
fn reregister(&mut self, io: &Evented, interest: EventSet, opt: PollOpt) -> Result<()>
fn deregister(&mut self, io: &Evented) -> Result<()>
fn timeout_ms(&mut self, delay: u64) -> Result<Timeout, TimerError>
Add timeout
This method is deprecated use return value of your state machine's action to set a timeout
fn clear_timeout(&mut self, token: Timeout) -> bool
Clear timeout
This method is deprecated (with timeout_ms) use return value of your state machine's action to change a timeout
fn notifier(&self) -> Notifier
Create a Notifier
that may be used to wakeup
enclosed state machine
fn now(&self) -> Time
Time of the current loop iteration
This is a time that needs to be used for timeouts. It's cheap to use
fn estimate_system_time(&self, time: Time) -> SystemTime
Returns the SystemTime that corresponds to the Time in this loop
Note: this is an estimate, because we use monotonic time under the
hood, but SystemTime
is a subject for adjustments of the system
clock.
I.e. it is fine to use this time to present it to the user, but it's wrong to rely on it in code.
