Struct Synthetic 

pub struct Synthetic { /* private fields */ }

An executor that answers from a caller-supplied function instead of running anything.

Named rather than a blanket impl over FnMut on purpose. The seam this replaces had exactly such a blanket impl, which meant every test got a fake without ever choosing one, and the trait looked exercised while no implementation had ever run a process. Reaching for a fake is now a thing you can see in the source.

Implementations

impl Synthetic

pub fn passing() -> Self

An executor whose every verdict is Verdict::Passed.

pub fn failing_labels(labels: &[&str]) -> Self

An executor that fails exactly the jobs whose label is listed and passes the rest.

The shape most queue tests need: “change 7 breaks the build”.

pub fn new(answer: impl FnMut(&Job) -> Verdict + Send + 'static) -> Self

An executor answering from answer.

Trait Implementations

impl CiExecutor for Synthetic

fn info(&mut self) -> Result<ExecutorInfo, ExecutorError>

Identity and protocol version. Called once before any job, so a mismatched provider is refused before it can return a verdict that means something else than it appears to.

fn run(&mut self, jobs: &[Job]) -> Result<Vec<Verdict>, ExecutorError>

Runs one train’s worth of jobs. The provider chooses its own concurrency.

impl Debug for Synthetic

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

Formats the value using the given formatter.
