Why a key file was not saved or loaded.

Variants

Io(Error)

Reading or writing the file failed.

NotRegular

The path names something other than a regular file, directly or through a symlink.

Owner

Another user than the effective user owns the file.

Permissions

The file’s group or others can read it.

TooLarge

The file is longer than 64 KiB, which no key file is.

BadKeyFile

The file is not a key file in the seed form.

WrongPurpose(Purpose)

The file holds a key for another purpose, named here.

WrongProfile(Profile)

The file holds a key for another profile, named here.

WrongAlgorithms

The key’s halves do not fit its profile.

WrongKeySize

The RSA-PSS half is not a 4,096-bit key with exponent 65537.

PrivateKeyInvalid

A private key does not decode.

PublicKeyMismatch

A stored public key is not the one its private key derives.

RoundTripFailed

The key does not sign and verify as a whole.

KeyStore(KeyStoreError)

The key store could not save or load the key.

Generate(KeyError)

A new key could not be made.

Trait Implementations

impl Debug for KeyFileError

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

Formats the value using the given formatter.

impl Display for KeyFileError

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

Formats the value using the given formatter.

impl Error for KeyFileError

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 KeyFileError

fn from(e: Error) -> Self

Converts to this type from the input type.
