HeardBugs

coven_foundation::task

Struct HeardBugs 

Source 
pub struct HeardBugs { /* private fields */ }
Expand description

Keeps every bug it hears of, and logs each at error, as an app’s crash reporter would: the sink a test gives coven. A test that expects a bug takes it; one left untaken when the sink drops fails the test, so a bug no test expected never passes unseen.

Implementations§

Source§

impl HeardBugs

Source

pub fn shared() -> Arc<Self>

A sink that has heard nothing yet, to share with coven.

Source

pub fn on_next_report(&self, hook: impl FnOnce(&Bug) + Send + 'static)

Run hook as the next bug is heard, inside its report: for a test that acts at the moment the reporter hands a bug over.

Source

pub fn take(&self) -> Vec<Bug>

Every bug heard since the last take, in the order heard.

Source

pub async fn next(&self) -> Bug

Wait for the first bug not yet taken, and take it: for a test whose bug reaches the sink after the call it made returned.
