Enum Error

#[non_exhaustive]
pub enum Error {
    Io(Error),
    InvalidScryptParams,
    ScryptKeyDerivation,
    Decryption,
    Utf8(FromUtf8Error),
    BadMagic(Vec<u8>),
    BadVersion {
        highest_supported_version: u8,

    },
}

Backup processing error.

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.

Io(Error)

I/O error.

InvalidScryptParams

Invalid parameters to the Scrypt key derivation.

ScryptKeyDerivation

Scrypt key derviation failed.

Decryption

AES-GCM decryption error.

Utf8(FromUtf8Error)

Unicode decode error.

BadMagic(Vec<u8>)

Magic value is incorrect.

This file is either corrupted or not a NetHSM backup.

BadVersion

Version number is not recognized.

This library supports only version 0 backups.

Fields

highest_supported_version: u8

backup_version: Vec<u8>

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<FromUtf8Error> for Error

fn from(source: FromUtf8Error) -> Self

Converts to this type from the input type.
