Enum ExternalCommandsUnavailable 

pub enum ExternalCommandsUnavailable {
    NotCompiled,
    ConfiguredOff,
}

Why kaish will not run an external command for this dispatch — distinct from “not found in PATH”, which is a different condition entirely (see crate::tools::builtin::spawn::virtual_cwd_error for that one).

The two variants name different audiences, not just different remedies: Self::NotCompiled is a build-time fact only whoever built this binary can change; Self::ConfiguredOff is a runtime policy an embedder set and can change. A caller must not collapse them into one message.

Lives here (not behind #[cfg(feature = "subprocess")]) because both Kernel::try_execute_external and dispatch.rs’s test-only BackendDispatcher::try_external need it from their not(subprocess) arm too, where the spawn module — gated on that same feature — is not compiled in.

Variants

NotCompiled

This binary was built without the subprocess capability.

ConfiguredOff

This binary has the capability, but this kernel’s configuration turned it off.

Implementations

impl ExternalCommandsUnavailable

pub fn condition(self) -> &'static str

The condition, named precisely and completely — no remedy. A remedy depends on the embedder’s own tool surface, which kaish cannot see (one caller’s fix is “use the other tool”; another’s is “reconfigure the kernel”), so the message stops at the fact.
