Struct SessionDeadline 

pub struct SessionDeadline { /* private fields */ }

The hard limit a session runs under: its own mur run --deadline, or the moment it inherited from the formation or capsule that launched it.

Both clocks are read once, at the session’s start. The monotonic one is what the runtime enforces and counts down against; the wall one is only what at is spelled from, so a clock change during the session moves neither the enforcement nor left_secs.

Implementations

impl SessionDeadline

pub fn after(started: Instant, started_wall: SystemTime, secs: u64) -> Self

The deadline secs after a start read as started and started_wall. A secs above MAX_DEADLINE_SECS is taken as that bound.

pub fn until( started: Instant, started_wall: SystemTime, at_wall: SystemTime, ) -> Self

The inherited deadline at the wall moment at_wall, for a session whose start was read as started and started_wall. What is left is at_wall - started_wall: zero when the moment has passed, and at most MAX_DEADLINE_SECS, beyond which at is that bound.

pub fn from_unix_millis( started: Instant, started_wall: SystemTime, millis: u64, ) -> Self

SessionDeadline::until the moment millis milliseconds after the Unix epoch, as INHERITED_DEADLINE_FLAG carries it. A moment the wall clock cannot hold is taken as the bound.

pub fn at_unix_millis(&self) -> u64

at in whole milliseconds since the Unix epoch, the value INHERITED_DEADLINE_FLAG carries. Truncated, so the moment a session inherits is never later than this one and spells the same second.

pub fn earliest(own: Option<Self>, inherited: Option<Self>) -> Option<Self>

The session’s deadline: the earlier of its own and the inherited one, the inherited one on a tie, and None when it has neither. Both must have been read against the same start.

pub fn secs(&self) -> u64

Seconds from the session’s start to at: the --deadline value for an own deadline, and rounded up, 0 once passed, for an inherited one.

pub fn source(&self) -> DeadlineSource

Where the deadline came from.

pub fn at_rfc3339(&self) -> String

When the runtime ends the session, as RFC 3339 UTC to the second.

pub fn left(&self, now: Instant) -> Duration

How long is left at now; zero once the deadline has passed.
