Enum GrantError 

pub enum GrantError {
    BadPrefix,
    BadBase64,
    BadPayload,
    BadSignature,
}

Failure modes for decoding a dcap1: token.

Variants

BadPrefix

The string does not start with the dcap1: prefix — not a delegation token (or a future/foreign version).

BadBase64

The body is not valid base64url.

BadPayload

The decoded bytes are not a well-formed postcard CapabilityGrant (truncated or corrupt).

BadSignature

The embedded owner signature is not a well-formed 65-byte ECDSA signature, so no owner can be recovered.

Trait Implementations

impl Debug for GrantError

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

Formats the value using the given formatter.

impl Display for GrantError

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

Formats the value using the given formatter.

impl Eq for GrantError

impl Error for GrantError

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<GrantError> for GrantOwnerError

fn from(source: GrantError) -> Self

Converts to this type from the input type.

impl PartialEq for GrantError

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

Equality operator ==.
