Enum OCatchStrategy

Source
pub enum OCatchStrategy {
    StdCombined,
    StdSeparately,
}
Expand description

Determines the strategy that is used to get STDOUT, STDERR, and “STDCOMBINED”. Both has advantages and disadvantages.

Variants§

§

StdCombined

Catches all output lines of STDOUT and STDERR in correct order on a line by line base. There is no way to find out STDOUT-only or STDERR-only lines.

§

StdSeparately

Catches all output lines from STDOUT and STDERR separately. There is also a “STDCOMBINED” vector, but the order is not 100% correct. It’s only approximately correct on a best effort base. If between each STDOUT/STDERR-alternating output is ≈100µs (a few thousand cycles) it should be definitely fine, but there is no guarantee for that. Also the incorrectness is not deterministic. This is because STDOUT and STDERR are two separate streams. Scheduling and buffering result in different results.
