}

Fields

steps: Vec<(&'static str, u64)>

Implementations

impl BootTimings

pub fn new() -> Self

pub fn accounted_ms(&self) -> u64

Sum of every recorded step. Steps may nest (a wrapped pass calling another wrapped pass), in which case this double-counts the inner one — which is why the summary reports it alongside the wall-clock total rather than deriving one from the other.

pub fn total_ms(&self) -> u64

Wall-clock since BootTimings::new — i.e. since srv started timing, not since process start.

pub fn summary(&self) -> String

total=412ms accounted=350ms | open_stores=210ms registry_session_backfill=88ms ...

Steps are listed slowest-first: the point of reading this line is finding what to move off the boot path, and that is always the top of the list.

Trait Implementations

fn default() -> Self

Returns the “default value” for a type.
