Struct CustomFact 

pub struct CustomFact {
    pub argv: Vec<String>,
}

Fact-kind body for custom. Spawns argv as a child process rooted at the repo; the process’s stdout (trimmed of trailing whitespace) becomes the fact’s String value. A non-zero exit code resolves to the empty string; timeouts and spawn failures do the same. No shell is invoked — argv is passed to execve (or the platform equivalent) verbatim.

Security: custom facts are only allowed in the user’s own top-level config. Any extends: ancestor that declares one is rejected at load time — otherwise a malicious ruleset could execute arbitrary code just by being fetched.

Fields

argv: Vec<String>

Program and arguments. argv[0] is looked up through PATH if it’s not an absolute or relative-with-separator path.
