Enum HandoffTokenError 

pub enum HandoffTokenError {
    Random(String),
    PendingLimitReached {
        max_pending_tokens: usize,
    },
    CollisionExhausted {
        attempts: usize,
    },
    TokenMismatch,
    TokenExpired,
    TokenNotPending,
}

Errors raised while issuing or consuming handoff tokens.

Variants

Random(String)

Random byte generation failed.

PendingLimitReached

The pending token set is full.

Fields

max_pending_tokens: usize

Maximum pending tokens allowed.

CollisionExhausted

All random candidates collided with existing pending tokens.

Fields

attempts: usize

Number of random candidates attempted.

TokenMismatch

The backend presented a token that does not match the expected handoff.

TokenExpired

The expected token existed but exceeded its TTL.

TokenNotPending

The expected token is unknown or has already been consumed.

Trait Implementations

impl Clone for HandoffTokenError

fn clone(&self) -> HandoffTokenError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HandoffTokenError

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

Formats the value using the given formatter.

impl Display for HandoffTokenError

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

Formats the value using the given formatter.

impl Eq for HandoffTokenError

impl Error for HandoffTokenError

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 HandoffTokenError

fn from(value: Error) -> Self

Converts to this type from the input type.

impl From<HandoffTokenError> for HandoffRejectionReason

fn from(value: HandoffTokenError) -> Self

Converts to this type from the input type.

impl PartialEq for HandoffTokenError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
