Struct BaselineManager 

pub struct BaselineManager { /* private fields */ }

Manages baseline storage in .benches/ directory

Implementations

impl BaselineManager

pub fn new() -> Result<Self, Error>

Create a new baseline manager

By default, uses .benches/ in the current directory

pub fn with_root_dir<P: AsRef<Path>>(root_dir: P) -> Result<Self, Error>

Create a baseline manager with a custom root directory

pub fn save_baseline( &self, crate_name: &str, result: &BenchResult, was_regression: bool, ) -> Result<(), Error>

Save a benchmark result as a baseline (creates new timestamped file)

pub fn load_baseline( &self, crate_name: &str, benchmark_name: &str, ) -> Result<Option<BaselineData>, Error>

Load the most recent baseline for a specific benchmark

pub fn has_baseline(&self, crate_name: &str, benchmark_name: &str) -> bool

Check if a baseline exists for a benchmark

pub fn list_runs( &self, crate_name: &str, benchmark_name: &str, ) -> Result<Vec<String>, Error>

List all run timestamps for a specific benchmark

pub fn load_run( &self, crate_name: &str, benchmark_name: &str, timestamp: &str, ) -> Result<Option<BaselineData>, Error>

Load a specific run by timestamp

pub fn list_baselines(&self, crate_name: &str) -> Result<Vec<String>, Error>

List all baselines for a crate

pub fn load_recent_baselines( &self, crate_name: &str, benchmark_name: &str, count: usize, ) -> Result<Vec<BaselineData>, Error>

Load last N baseline runs for a benchmark

Returns the most recent baseline runs in chronological order (oldest first). Excludes runs that were flagged as regressions to keep the baseline clean. This is used for statistical window comparison.
