Enum PreflightError 

pub enum PreflightError {
    Unreachable(Error),
    Rejected(TransportError),
}

Why a preflight authorization check failed (see verify_daemon_authorization). The two cases need DIFFERENT remediation — “start the daemon / check the network” vs “get your key enrolled” — so they are distinguished at the type level instead of by string-matching an io::ErrorKind (a dial refusal and a handshake rejection both involve connection-level I/O and must not be conflated).

Variants

Unreachable(Error)

The daemon could not be reached at all (dial failure).

Rejected(TransportError)

The daemon was reached but the Noise IK handshake failed: the daemon either does not hold the expected server key, or its ACL did not admit this client’s transport key. (An IK handshake is the ONLY probe that can detect the ACL rejection — the daemon aborts the handshake before message 2 — which is why this preflight runs IK even on a first-contact flow that already probed with XX.)

Trait Implementations

impl Debug for PreflightError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for PreflightError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for PreflightError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
