Trait CommandExt

pub trait CommandExt {
    // Required methods
    fn checked_output(&mut self) -> Result<Output, Error>;
    fn checked_status(&mut self) -> Result<(), Error>;
}

Extension to std::process::Command adding versions of the output/status functions which also fail/error with a non-success exit status

Required Methods

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

fn checked_status(&mut self) -> Result<(), Error>

Behaves like std::process::Command::status but also checks the exit status for success, returning a error if it did not succeed

Error

if the exit status is not successful or a io::Error was returned from Command::output
