Struct Context
pub struct Context<'a> {
pub now_unix_ms: u64,
pub session: Option<&'a str>,
pub task_open: Option<&'a dyn Fn(&str) -> bool>,
}Expand description
What liveness depends on where a decision is made.
Fields§
§now_unix_ms: u64Wall clock, Unix milliseconds.
session: Option<&'a str>The current session. None where sessions are not known (a relay): a
session grant then counts as live, and the device that holds the session
is the one that refuses after it ends.
task_open: Option<&'a dyn Fn(&str) -> bool>Whether a task is open. None where tasks are not known.
Implementations§

pub const fn at(now_unix_ms: u64) -> Context<'a>
pub fn at_time(now: SystemTime) -> Context<'a>
pub fn at_time(now: SystemTime) -> Context<'a>
At the wall-clock time now; the Unix epoch for a time before it.
pub const fn in_session(self, session: &'a str) -> Context<'a>
pub const fn with_tasks( self, task_open: &'a dyn Fn(&str) -> bool, ) -> Context<'a>

fn into_any(self: Box<T>) -> Box<dyn Any>
Convert
Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can
then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.§fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert
Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be
further downcast into Rc<ConcreteType> where ConcreteType implements Trait.§fn as_any(&self) -> &(dyn Any + 'static)
fn as_any(&self) -> &(dyn Any + 'static)
Convert
&Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &Any’s vtable from &Trait’s.§fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
Convert
&mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &mut Any’s vtable from &mut Trait’s.§impl<T> Instrument for T
