Enum AttestationError 

pub enum AttestationError {
    Canonical(Error),
    HashMismatch {
        expected: String,
        actual: String,
    },
    BadSignature,
    InvalidBase64(DecodeError),
    WrongSignatureLength(usize),
    UnsupportedAlgorithm(String),
    UntrustedKey(String),
}

Anything that can go wrong inside the crate.

Variants

Canonical(Error)

Serialising the input doc to canonical JSON failed.

HashMismatch

signed_hash didn’t match the recomputed canonical hash for the body supplied at verify time.

Fields

expected: String

Hash recorded on the attestation.

actual: String

Hash recomputed from the body the caller supplied.

BadSignature

Signature didn’t validate against the public key.

InvalidBase64(DecodeError)

Base64 decoding the signature field failed.

WrongSignatureLength(usize)

Signature bytes weren’t 64 bytes after decode.

UnsupportedAlgorithm(String)

The attestation declared algorithm we don’t know how to verify.

UntrustedKey(String)

The caller asked crate::Verifier::verify for a key URL that wasn’t in the trust set.

Trait Implementations

impl Debug for AttestationError

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

Formats the value using the given formatter.

impl Display for AttestationError

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

Formats the value using the given formatter.

impl Error for AttestationError

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<DecodeError> for AttestationError

fn from(source: DecodeError) -> Self

Converts to this type from the input type.

impl From<Error> for AttestationError

fn from(source: Error) -> Self

Converts to this type from the input type.
