ScopedPipefail

Struct ScopedPipefail 

Source
pub struct ScopedPipefail(/* private fields */);
Expand description

Overrides the pipefail mode in the current thread, while the value is in scope.

Each override restores the previous value when dropped, so they can be nested. Since overrides are thread-local, these values can’t be sent across threads.

// Must give the variable a name, not just `_`
let _debug = ScopedPipefail::set(false);
run_cmd!(false | true)?; // Will have pipefail off
