Variants

BadEncoding

A public NKey was not valid base32-nopad text.

BadPublicKeyLen(usize)

A public key was not the expected 32 bytes.

UnsupportedPrefix(char)

A decoded NKey carried a prefix letter that is not a known public role. The supported public-key roles are A account, C cluster, N server, O operator, U user, and X curve/x25519.

UnexpectedPrefix

A public NKey decoded cleanly, but its NkeyType did not match the role required for the claim shape being minted.

Fields

expected: NkeyType

actual: NkeyType

Json(Error)

JSON serialization failed (should not happen for these types).

InvalidClaims(String)

A caller-supplied claim document is not a NATS JWT claim object.

MalformedJwt(String)

A compact JWT was not a valid NATS JWT.

BadSignatureLen(usize)

A compact JWT signature segment did not decode to a 64-byte Ed25519 signature.

UnexpectedXKeyPrefix(NkeyType)

A NATS xkey operation was given a non-curve public NKey.

BadXKeyVersion

A NATS xkey ciphertext did not carry the xkv1 version prefix.

BadXKeyCiphertextLen(usize)

A NATS xkey ciphertext was too short to contain version, nonce, and tag.

XKeyRandomnessFailed

The caller-supplied RNG failed while generating a NATS xkey nonce.

XKeySealFailed

NATS xkey encryption failed.

XKeyOpenFailed

NATS xkey authentication failed on open.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 From<Error> for Error

fn from(e: Error) -> Self

Converts to this type from the input type.
