Module runner 

Small subprocess runner.

Wraps std::process::Command with:

• A timeout guard that SIGTERMs then SIGKILLs on overrun.
• Preserved stderr so crate::Error::CommandFailed can surface the underlying tool’s own diagnostics.
• CommandRunner trait so tests can inject a fake binary (see #[cfg(test)] in each module).

Structs

RunOptions

Configuration for a single subprocess.

RunResult

Output of a completed subprocess.

Constants

TIMEOUT_STATUS

Status reported for a subprocess that was killed by its timeout. Exposed so callers and tests can branch on it without magic numbers.

Functions

read_line_interactive

Read stdin from an interactive TTY, returning a trimmed line.

run

Runs a command with RunOptions and returns RunResult.

run_expect_success

Convenience helper: run a command that should succeed, otherwise wrap into Error::CommandFailed.

which

Locate a binary on PATH. Returns the full path or Error::MissingDependency.
