Enum PepperError 

#[non_exhaustive]
pub enum PepperError {
    UnknownVersion(KeyVersion),
    EmptyKeyset,
    KeyTooShort {
        version: KeyVersion,
        actual: usize,
        minimum: usize,
    },
    Backend(String),
}

Errors returned by Pepper implementations.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

UnknownVersion(KeyVersion)

The provider does not hold a key for the requested version.

EmptyKeyset

The provider has no keys registered at all — typically a builder configuration error.

KeyTooShort

A registered key was shorter than the 16-byte safety floor.

Fields

version: KeyVersion

Version that failed validation.

actual: usize

Actual length in bytes.

minimum: usize

Required minimum.

Backend(String)

The underlying KMS / HSM backend returned an error.

Trait Implementations

impl Debug for PepperError

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

Formats the value using the given formatter.

impl Display for PepperError

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

Formats the value using the given formatter.

impl Error for PepperError

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.
