Struct BenchmarkBaseline 

pub struct BenchmarkBaseline {
    pub crate_name: String,
    pub git_hash: Option<String>,
    pub timestamp: String,
    pub results: Vec<BenchmarkResult>,
}

A collection of BenchmarkResults representing either a stored baseline or a fresh measurement run.

Fields

crate_name: String

Name of the crate or component being benchmarked.

git_hash: Option<String>

Git commit hash at the time of recording, if available.

timestamp: String

ISO 8601 timestamp string (e.g. "2026-01-01T00:00:00Z").

results: Vec<BenchmarkResult>

Individual benchmark results.

Implementations

impl BenchmarkBaseline

pub fn new(crate_name: impl Into<String>) -> Self

Create an empty baseline for crate_name.

git_hash is populated from the GIT_HASH environment variable when present; otherwise None is stored.

pub fn add(&mut self, result: BenchmarkResult)

Append a BenchmarkResult to this baseline.

pub fn find(&self, name: &str) -> Option<&BenchmarkResult>

Return a reference to the BenchmarkResult with the given name, or None if not present.

pub fn save(&self, path: &Path) -> Result<()>

Persist the baseline to a JSON file at path.

Errors

Propagates I/O and serialisation errors as std::io::Error.

pub fn load(path: &Path) -> Result<Self>

Load a baseline from a JSON file at path.

Errors

Propagates I/O and deserialisation errors as std::io::Error.

pub fn to_markdown(&self) -> String

Return a summary line for each result in Markdown table form.
