Struct ExperimentTracker 

pub struct ExperimentTracker<B: TrackingBackend> { /* private fields */ }

Experiment tracker

Manages multiple runs under a single experiment name. Persists run data through a pluggable TrackingBackend.

Implementations

impl<B: TrackingBackend> ExperimentTracker<B>

pub fn new(experiment_name: impl Into<String>, backend: B) -> Self

Create a new tracker for the given experiment name

pub fn add_tag(&mut self, key: impl Into<String>, value: impl Into<String>)

Add an experiment-level tag

pub fn experiment_name(&self) -> &str

Get the experiment name

pub fn tags(&self) -> &HashMap<String, String>

Get experiment-level tags

pub fn start_run(&mut self, run_name: Option<&str>) -> Result<String>

Start a new run, optionally with a human-readable name

Returns the run ID.

pub fn end_run(&mut self, run_id: &str, status: RunStatus) -> Result<()>

End a run with the given status, persisting it to the backend

pub fn log_param(&mut self, run_id: &str, key: &str, value: &str) -> Result<()>

Log a single parameter (hyperparameter)

pub fn log_params( &mut self, run_id: &str, params: &HashMap<String, String>, ) -> Result<()>

Log multiple parameters at once

pub fn log_metric( &mut self, run_id: &str, key: &str, value: f64, step: u64, ) -> Result<()>

Log a metric value at a given step

pub fn log_artifact(&mut self, run_id: &str, path: &str) -> Result<()>

Log an artifact path

pub fn get_run(&self, run_id: &str) -> Result<Run>

Retrieve a run by ID

Checks active (in-memory) runs first, then falls back to the backend.

pub fn list_runs(&self) -> Result<Vec<Run>>

List all runs (active + persisted)

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

Formats the value using the given formatter.
