Enum tox_encryptsave::DecryptionError

pub enum DecryptionError {
    Null,
    InvalidLength,
    BadFormat,
    KeyDerivation(KeyDerivationError),
    Failed,
}

Error when trying to decrypt data.

Variants

Null

Data to be decrypted is empty.

InvalidLength

There's not enough data to decrypt.

BadFormat

Provided data has invalid format, incompatible with TES.

KeyDerivation(KeyDerivationError)

Deriving key failed.

Failed

Failure due to encrypted data being invalid.

Can happen when:

• data is invalid
  • note that it can happen due to bitrot – i.e. even a single byte getting corrupted can render data ~impossible to decrypt
• not all encrypted bytes were provided
• some bytes that aren't encrypted were provided after encrypted bytes

impl Eq for DecryptionError

impl Fail for DecryptionError

fn name(&self) -> Option<&str>

Returns the "name" of the error.

fn cause(&self) -> Option<&dyn Fail>

Returns a reference to the underlying cause of this failure, if it is an error that wraps other errors.

fn backtrace(&self) -> Option<&Backtrace>

Returns a reference to the Backtrace carried by this failure, if it carries one.

fn context<D>(self, context: D) -> Context<D> where
    D: Display + Send + Sync + 'static, 

Provides context for this failure.

fn compat(self) -> Compat<Self>

Wraps this failure in a compatibility wrapper that implements std::error::Error.

impl From<KeyDerivationError> for DecryptionError

fn from(err: KeyDerivationError) -> DecryptionError

Performs the conversion.

impl PartialEq<DecryptionError> for DecryptionError

fn eq(&self, other: &DecryptionError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &DecryptionError) -> bool

This method tests for !=.
