mcp.exec.RunOutcome

Rust

enum mcp.exec.RunOutcome enum [source] ¶ enum [source] ¶ enum mcp.exec.RunOutcome: How a run finished.

Split from the wait outcomes rather than shared with them: a run cannot match a pattern and a wait cannot report a missing shell, and a vocabulary carrying both would have an agent checking for answers that never come.

Members

Completed constant [source] ¶ constant [source] ¶ Completed: The command ran to completion and reported its status.

Deadline constant [source] ¶ constant [source] ¶ Deadline: The time the caller allowed ran out.

This ends the waiting, not the command. The pane stays reserved for it until it ends, so other pane input is refused; send_keys with keys ["C-c"] alone interrupts it.

PaneClosed constant [source] ¶ constant [source] ¶ PaneClosed: The pane stopped writing for good.

Cancelled constant [source] ¶ constant [source] ¶ Cancelled: The client withdrew the request while the run was still going.

NoShell constant [source] ¶ constant [source] ¶ NoShell: The pane never acknowledged the command.

The keys were sent but the opening sentinel never came back. That is what a pane looks like when it is not at a shell prompt: sitting in an editor or a REPL, or still running something an earlier call left behind. The text was typed into whatever is there.
The evidence is absence, so a deadline too short for the pane's shell to have echoed anything yet looks the same. Read it as "nothing came back in the time allowed" and check the pane with snapshot_pane before concluding it is stuck.
