Enum ResolveError 

pub enum ResolveError {
    Parse(String),
    Transport(String),
    Rpc(String),
    NotFound,
    RootRequired,
    VerifyFailed(String),
    DecryptFailed,
}

A hard, fail-closed resolution failure. Distinct from ResolveOutcome::Unreachable (the network-down state) and ResolveOutcome::IntegrityFailure (bytes fetched but unverifiable).

Variants

Parse(String)

The input was not a syntactically valid DIG URN.

Transport(String)

A transport-level failure talking to a specific endpoint (DNS, TLS, connection, timeout, malformed HTTP). Not “every tier down” (that is ResolveOutcome::Unreachable).

Rpc(String)

The RPC endpoint returned a protocol error, or a response the resolver cannot interpret.

NotFound

The resource does not exist in the store at the resolved root. A hard, fail-closed verdict.

RootRequired

A rootless URN was resolved over the untrusted blind tier, where the trust root cannot be established without trusting the gateway. Pin a root in the URN, or resolve via a loopback node. Fail-closed — the resolver will NOT verify against a gateway-asserted root.

VerifyFailed(String)

The served ciphertext failed integrity verification against the chain-anchored root (tampered bytes, a non-chaining proof, or a decoy from a wrong store). FAIL-CLOSED: bytes discarded.

DecryptFailed

The verified ciphertext did not decrypt under the URN’s key (AEAD tag failure — wrong key/salt or corruption), or an untrusted chunk-length plan was inconsistent. FAIL-CLOSED.

Trait Implementations

impl Clone for ResolveError

impl Eq for ResolveError

impl Error for ResolveError

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.

impl PartialEq for ResolveError

fn eq(&self, other: &ResolveError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
