Module exec 

Exec-related protocol message payloads.

Structs

ExecExited

Notification that a command has exited.

ExecFailed

Notification that a command failed to start (the user’s program never got to run). Distinct from ExecExited, which means the process ran and reported an exit code.

ExecLimits

Runtime-owned execution policy advertised in Ready. Effective policy shared by every execution in one sandbox.

ExecOutputAck

Acknowledges cumulative output consumed by the SDK, including per-chunk overhead.

ExecRequest

Request to execute a command in the guest.

ExecResize

Request to resize the PTY of a running command.

ExecRlimit

A POSIX resource limit to apply to a spawned process.

ExecSignal

Request to send a signal to a running command.

ExecStarted

Confirmation that a command has been started.

ExecStderr

Stderr data from a running command.

ExecStdin

Stdin data sent to a running command.

ExecStdinAck

Acknowledges cumulative bytes written into the child’s stdin pipe.

ExecStdinError

Notification that an ExecStdin write to the child’s stdin failed. The most common cause is the child closing its read end (EPIPE); the session is otherwise alive and may still produce output and an exit code, so this is delivered as a non-terminal event.

ExecStdout

Stdout data from a running command.

Enums

ExecFailureKind

Coarse classification of an ExecFailed cause. The CLI’s stage-to-hint mapper keys off this; the SDK exposes it directly for programmatic consumers.

RlimitResource

POSIX resource limit identifiers.

Constants

EXEC_OUTPUT_EVENT_OVERHEAD

Window charge for each output chunk, bounding even very small writes. Memory-accounting charge in addition to each output payload.

MAX_EXEC_CONTROL_BYTES

Maximum encoded execution acknowledgement, signal or resize envelope.
