Variants

Start

Command has started execution

Done(Option<i32>)

Command has exited. Returns the exit status (if available) of the command

Stdout(LineEnding, Vec<u8>)

A single line of standard out formatted as a byte vector. The line ending is included in the enum but not in the byte vector

Stderr(LineEnding, Vec<u8>)

A single line of standard error formatted as a byte vector. The line ending is included in the enum but not in the byte vector

Error(Error)

An error has occurred with the command (usually a malformed command or I/O error). This doesn’t include commands that fail via exit status. That is reported via OutputMessagePayload::Done.
