rustls reports protocol errors using this type.

Variants

InappropriateMessage

We received a TLS message that isn't valid right now. expect_types lists the message types we can expect right now. got_type is the type we found. This error is typically caused by a buggy TLS stack (the peer or this one), a broken network, or an attack.

Fields of InappropriateMessage

expect_types: Vec<ContentType>

Which types we expected

got_type: ContentType

What type we received

InappropriateHandshakeMessage

We received a TLS handshake message that isn't valid right now. expect_types lists the handshake message types we can expect right now. got_type is the type we found.

Fields of InappropriateHandshakeMessage

expect_types: Vec<HandshakeType>

Which handshake type we expected

got_type: HandshakeType

What handshake type we received

CorruptMessage

The peer sent us a syntactically incorrect TLS message.

CorruptMessagePayload(ContentType)

The peer sent us a TLS message with invalid contents.

NoCertificatesPresented

The peer didn't give us any certificates.

DecryptError

We couldn't decrypt a message. This is invariably fatal.

PeerIncompatibleError(String)

The peer doesn't support a protocol version/feature we require. The parameter gives a hint as to what version/feature it is.

PeerMisbehavedError(String)

The peer deviated from the standard TLS protocol. The parameter gives a hint where.

AlertReceived(AlertDescription)

We received a fatal alert. This means the peer is unhappy.

WebPKIError(Error)

The presented certificate chain is invalid.

InvalidSCT(Error)

The presented SCT(s) were invalid.

General(String)

A catch-all error for unlikely errors.

FailedToGetCurrentTime

We failed to figure out what time it currently is.

HandshakeNotComplete

This function doesn't work until the TLS handshake is complete.

PeerSentOversizedRecord

The peer sent an oversized record/fragment.

NoApplicationProtocol

An incoming connection did not support any known application protocol.

Trait Implementations

impl Clone for TLSError

fn clone(&self) -> TLSError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TLSError

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

Formats the value using the given formatter.

impl Display for TLSError

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

Formats the value using the given formatter.

impl Error for TLSError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

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

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl PartialEq<TLSError> for TLSError

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

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

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

This method tests for !=.
