Extension to std::process::Command
adding versions of the output/status
functions which also fail/error with a non-success exit status
Required Methods§
Sourcefn checked_output(&mut self) -> Result<Output, Error>
fn checked_output(&mut self) -> Result<Output, Error>
Behaves like std::process::Command::output
but also checks the
exit status for success. The Output
produced in case of a
command returning a failing exit status is included into the
error.
§Error
if the exit status is not successful or a io::Error
was returned
from Command::output
