Struct ExecutionOrigin 

pub struct ExecutionOrigin { /* private fields */ }

The supervisor-minted origin of one real execution.

Implementations

impl ExecutionOrigin

pub fn try_mint() -> Option<Self>

Mint an origin now, returning None when the host boot clock is unreadable.

pub fn mint() -> Self

Mint an origin now, panicking on a host without a readable boot clock.

A supervisor that wants to report the failure rather than abort calls ExecutionOrigin::try_mint instead. This form exists for the bootstrap path, where a host whose monotonic clock cannot be read cannot time an execution at all and there is nothing to degrade to.

pub const fn new(boot: BootId, boot_ns: u64, timeline: TimelineId) -> Self

Rebuild an origin from its typed fields.

The counterpart to the accessors below, for a consumer that already holds the three values: a decoded launch record, or a test pinning an origin to a specific boot.

pub const fn boot(self) -> BootId

The boot this origin was minted during.

pub const fn boot_ns(self) -> u64

Nanoseconds on the boot clock at execution start.

pub const fn timeline(self) -> TimelineId

The real execution’s timeline.

pub fn encode(self) -> String

Render as <boot>:<boot-ns>:<timeline>.

pub fn decode(value: &str) -> Option<Self>

Parse the launch representation without compatibility fallbacks.
