Enum RequestStateError 

#[non_exhaustive]
pub enum RequestStateError {
    WeakKey,
    ZeroTtl,
    TooLarge(usize),
    Malformed,
    UnsupportedVersion,

}

Errors produced while encoding or validating opaque MRTR request state.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

WeakKey

HMAC keys shorter than 256 bits do not meet this codec’s minimum.

ZeroTtl

The configured TTL must allow the state to live for some amount of time.

TooLarge(usize)

The serialized state exceeded the configured token-size limit.

Malformed

The token did not have the versioned three-part wire shape.

UnsupportedVersion

The token uses a codec version this server does not understand.

Integrity

The HMAC did not match the payload.

Expired

The token is no longer valid.

SubjectMismatch

A token bound to one authorization subject was used by another.

Encode(Error)

The state value could not be serialized.

Decode(Error)

The state value could not be decoded as the expected type.

Clock

The system clock is earlier than the Unix epoch.

Trait Implementations

impl Debug for RequestStateError

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

Formats the value using the given formatter.

impl Display for RequestStateError

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

Formats the value using the given formatter.

impl Error for RequestStateError

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.
