}

Aggregate phase-timing totals from the daemon’s PhaseProfiler.

Totals are in nanoseconds. Divide hit-path totals by hit_count and miss-path totals by miss_count to derive per-compile averages.

Use case: a perf harness collects this from a warm-rebuild session to identify which phase dominates the warm-side wall time (e.g. write_output_ns for artifact materialization vs depgraph_check_ns for depgraph lookups).

Fields

hit_count: u64

Number of cache-hit compiles that contributed to the hit-path totals.

miss_count: u64

Number of cache-miss compiles that contributed to the miss-path totals.

parse_args_ns: u64

Argument parsing.

build_context_ns: u64

Build compile context + register with depgraph.

hash_source_ns: u64

Source-file hash via the metadata cache fast path.

hash_headers_ns: u64

Header hashes via the metadata cache fast path.

depgraph_check_ns: u64

Depgraph verdict lookup.

request_cache_lookup_ns: u64

Request-level cache lookup.

cross_root_validate_ns: u64

Cross-root request validation.

artifact_lookup_ns: u64

In-memory artifact-store lookup.

write_output_ns: u64

Write cached outputs to disk (hardlink-first, copy fallback).

bookkeeping_ns: u64

Stats recording + session bookkeeping.

total_hit_ns: u64

Wall-clock total of the hit path.

compiler_exec_ns: u64

Run the actual compiler subprocess.

include_scan_ns: u64

Scan included files post-compile.

hash_all_ns: u64

Hash all inputs for the artifact key.

artifact_store_ns: u64

Persist the new artifact to disk.

total_miss_ns: u64

Wall-clock total of the miss path.

Trait Implementations

impl Clone for PhaseProfileSummary

fn clone(&self) -> PhaseProfileSummary

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PhaseProfileSummary

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PhaseProfileSummary

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<PhaseTotals> for PhaseProfileSummary

fn from(t: PhaseTotals) -> Self

Converts to this type from the input type.

impl PartialEq for PhaseProfileSummary

fn eq(&self, other: &PhaseProfileSummary) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for PhaseProfileSummary

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
