Struct RustWorkerServer 

pub struct RustWorkerServer { /* private fields */ }

The Rust Workers of one Cargo workspace a browser suite may start.

Implementations

impl RustWorkerServer

pub fn present(root: &Path) -> bool

Whether root holds a Rust Worker a suite could start.

pub fn prepare( root: &Path, workspace: &Path, run_id: &str, command: &[String], diagnostics: &mut dyn Write, ) -> Result<Vec<Self>, String>

Instrument the copy’s Worker crates and point their configurations at Supercov’s entry, one server per Cargo workspace. Empty when the project has no Rust Worker.

pub fn source_files(&self) -> usize

pub fn source_fingerprint(&self) -> String

The source this Worker was instrumented from: an image built from an earlier copy holds probes placed in other source.

pub fn environment(&self) -> BTreeMap<String, String>

What the suite’s environment needs: a lint on the rewritten source must not fail the Worker’s build under the crate’s own lint policy.

Capped at warn, not allow as for cargo test: Cargo learns which crate types a target supports from rustc’s “dropping unsupported crate type” warnings, and wasm32 drops dylib and proc-macro, so with every lint allowed it cannot read the answer and stops the build. The probes’ parentheses, the one lint they raise, are allowed by name.

pub fn publish( self, root: &Path, _evidence_run_id: &str, metadata: RunMetadata, served: &[ServedTest], diagnostics: &mut dyn Write, ) -> Result<Option<(PathBuf, RunMetadata)>, String>

Publish what the Workers ran as a Rust run of its own: each window credited, by time, to the one browser test whose span it overlaps; what no single test’s does is the run’s background. None when no Worker ran or no browser test reported.
