Struct CliBackend 

pub struct CliBackend { /* private fields */ }

The real backend: finds the binary once, then spawns it per call.

Implementations

impl CliBackend

pub fn discover() -> Result<Self, ExecError>

Find the binary and build a backend around it.

Order: the explicit override, then the search path, then the macOS application bundle. The override is first because an operator who names a path means it — if it is wrong, that is an error rather than a quiet fallback to some other Tailscale on the machine.

pub fn discover_with(override_path: Option<&OsStr>) -> Result<Self, ExecError>

Self::discover, with the override supplied rather than read from the environment, so a test can drive every branch.

pub fn at(binary: impl Into<PathBuf>) -> Self

A backend over a known binary. The stub-binary tests use this.

pub fn binary(&self) -> &Path
