Enum Error 

pub enum Error {
    HandshakeFailed,
    MessageLimitReached,
    EncryptionFailed,
    DecryptionFailed,
    InvalidTimestamp(u64, Range<u64>),
}

Errors relating to the handshake, or to encryption.

Variants

HandshakeFailed

An error indicating that the handshake failed.

We don’t provide detail on why the handshake failed, following a common precautionary principle. The basis of this reasoning is that:

• the application can’t meaningfully respond to different failure reasons,
• an adversary might gain an advantage by knowing the failure reason.

In other words, there’s only disadvantages and extra effort in doing so.

MessageLimitReached

An error indicating that no more messages can (safely) be sent.

In practice, you should never see this error, because the limit takes an ultra-astronomical amount of messages to reach.

EncryptionFailed

Encryption failed for some reason.

In practice, this error shouldn’t happen.

DecryptionFailed

Decryption failed.

This can happen if the message was corrupted, for some reason.

InvalidTimestamp(u64, Range<u64>)

The timestamp is not in the allowable bounds

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.
