Implementations

impl IdleObservation

pub fn result_lines( &self, warm: &ProcessUsage, labels: &BudgetLabels<'_>, ) -> String

The stable machine-readable lines the runtime-budget gate records, one figure per line: RESULT <key>=<number> <unit>, or RESULT <key>=unavailable <reason> when the host cannot report the figure (never a stand-in zero). resident_memory_bytes is the resident set at the end of the idle window. scale and what state the load the crate carried; scope is synthetic, real or installed.

resident_memory_bytes is the larger of the resident set warm (taken right after the load) and at the end of the idle window: an OS may compress or page out idle memory, and a ceiling must cover the loaded state, not only the reclaimed one. The two are also printed separately.

It also prints the single gate line RESULT budget crate=.. version=.. resident_bytes=.. idle_cpu_percent=.. wakeups_per_s=.. disk_ops_per_s=.. scale_unit=.. scale_count=.. (docs/RUNTIME-BUDGETS.md); a figure the host cannot report prints unavailable there, which the gate refuses, and is never replaced by zero.
