Struct ExecSyncOutput 

struct ExecSyncOutput {
    stdout: Vec<u8>,
    stderr: Vec<u8>,
    exit_code: i32,
    timed_out: bool,
}

The result of an exec_sync.

Fields

stdout: Vec<u8>

stderr: Vec<u8>

exit_code: i32

timed_out: bool

Implementations

impl ExecSyncOutput

const FRAMING_HEADROOM: usize

What the response keeps free for the framing of the gRPC message which carries it, see ExecSyncOutput::MAX_SIZE.

const MAX_SIZE: usize

The most output an exec_sync returns, stdout and stderr together, like conmon. The response has to fit into the 16 MiB gRPC messages of CRI-O and the kubelet, which also carry the framing.

fn cap(stdout: &mut Vec<u8>, stderr: &mut Vec<u8>)

Cut the output to ExecSyncOutput::MAX_SIZE. Each stream keeps up to half of it, and more of what the other one leaves, so that a large output of one does not drop the few lines of the other, like an error on stderr.
