Enum VcError 

pub enum VcError {
    InvalidSignature,
    Expired,
    UngroundedIssuer,
    DecodeTooShort,
    DecodeBadClaimCount,
}

Variants

InvalidSignature

The signature does not verify against the issuer key over the credential bytes.

Expired

now is past valid_until.

UngroundedIssuer

The issuer is an ungrounded artificial agent (no Principal) — agency.n3 G1’.

DecodeTooShort

The binary payload is too short to parse a Credential header.

DecodeBadClaimCount

The binary payload is too short for the declared claim count.

Trait Implementations

impl Debug for VcError

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

Formats the value using the given formatter.

impl Display for VcError

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

Formats the value using the given formatter.

impl Error for VcError

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 VcError

fn eq(&self, other: &VcError) -> 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.
