Enum ErsError 

pub enum ErsError {
    HashMismatch {
        expected: HashAlgorithm,
        actual: HashAlgorithm,
    },
    UntrustedTsa(String),
    BrokenChain(u32),
    UnsupportedAlgorithm(HashAlgorithm),
}

Errors during ERS operations.

Variants

HashMismatch

Hash algorithm mismatch.

Fields

expected: HashAlgorithm

Expected.

actual: HashAlgorithm

Actual.

UntrustedTsa(String)

TSA not trusted.

BrokenChain(u32)

Hash chain broken.

UnsupportedAlgorithm(HashAlgorithm)

The record uses an algorithm the verifier can’t hash with.

The evidence-record data model stores fixed 32-byte digests, which fits SHA-256 but not SHA-384 (48 bytes) or SHA-512 (64 bytes). Supporting those requires widening the hash fields to Vec<u8> — tracked as a follow-up. Verification refuses rather than truncating a stronger digest, which would weaken it.

Trait Implementations

impl Debug for ErsError

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

Formats the value using the given formatter.

impl Display for ErsError

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

Formats the value using the given formatter.

impl Error for ErsError

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>)
