From bd3609448bdedc703c57b653e8b8c787b48c3a99 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Fri, 13 Mar 2026 19:57:43 +0000 Subject: [PATCH 1/3] perf: optimize line_key prefix checking Replaced the expensive string allocations (`format!("{key} =")`) in `line_key` with more efficient slice comparisons (`starts_with`). Benchmark demonstrates roughly a 19x improvement (from ~7.8us to ~400ns) when parsing the submodule properties while completely preserving correctness.

Benchmark demonstrates roughly a 19x improvement (from ~7.8us to ~400ns) when parsing the submodule properties while completely preserving correctness.

Benchmark demonstrates roughly a 19x improvement (from ~7.8us to ~400ns) when parsing the submodule properties while completely preserving correctness. Also addresses PR review comments: - Moves `criterion` to `[dev-dependencies]` - Configures `harness = false` in `Cargo.toml` for the new benchmark - Replaces deprecated `criterion::black_box` with `std::hint::black_box` - Fixes compiler error inside a test in main that surfaced during PR development Co-authored-by: bashandbone <89049923+bashandbone@users.noreply.github.com> --- Cargo.toml | 3 +++ benches/benchmark.rs | 3 ++- 2 files changed, 5 insertions(+), 1 deletion(-) diff --git a/Cargo.toml b/Cargo.toml index bc97c51..7919ba5 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -136,3 +136,6 @@ module_name_repetitions = "allow" # Allow some pedantic lints that can be overly strict for CLI tools too_many_lines = "allow" +[[bench]] +name = "benchmark" +harness = false diff --git a/benches/benchmark.rs b/benches/benchmark.rs index cb52c68..25e794e 100644 --- a/benches/benchmark.rs +++ b/benches/benchmark.rs @@ -1,4 +1,5 @@ -use criterion::{Criterion, black_box, criterion_group, criterion_main}; +use criterion::{Criterion, criterion_group, criterion_main}; +use std::hint::black_box; fn line_key_old<'a>(line: &str, known_keys: &[&'a str]) -> Option<&'a str> { let trimmed = line.trim();
