    InvalidKeyLength {
        actual: usize,
    },
    MalformedEncoding,
    MalformedEpoch,
}

Variants

InvalidKeyLength

The vault-resolved key was not exactly 32 bytes.

Fields

actual: usize

The length of the supplied key material.

Trait Implementations

impl Debug for HistoryKeyError

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

Formats the value using the given formatter.

impl Display for HistoryKeyError

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

Formats the value using the given formatter.

impl Error for HistoryKeyError

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>)
