rustls reports protocol errors using this type.

Variants (Non-exhaustive)§

This enum is marked as 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.
§

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

§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

§expect_types: Vec<HandshakeType>

Which handshake type we expected

§got_type: HandshakeType

What handshake type we received

§

InvalidMessage(InvalidMessage)

The peer sent us a TLS message with invalid contents.

§

NoCertificatesPresented

The peer didn’t give us any certificates.

§

UnsupportedNameType

The certificate verifier doesn’t support the given type of name.

§

DecryptError

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

§

EncryptError

We couldn’t encrypt a message because it was larger than the allowed message size. This should never happen if the application is using valid record sizes.

§

PeerIncompatible(PeerIncompatible)

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

§

PeerMisbehaved(PeerMisbehaved)

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.

§

InvalidCertificate(CertificateError)

We saw an invalid certificate.

The contained error is from the certificate validation trait implementation.

§

InvalidCertRevocationList(CertRevocationListError)

A provided certificate revocation list (CRL) was invalid.

§

General(String)

A catch-all error for unlikely errors.

§

FailedToGetCurrentTime

We failed to figure out what time it currently is.

§

FailedToGetRandomBytes

We failed to acquire random bytes from the system.

§

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.

§

BadMaxFragmentSize

The max_fragment_size value supplied in configuration was too small, or too large.

§

Other(OtherError)

Any other error.

This variant should only be used when the error is not better described by a more specific variant. For example, if a custom crypto provider returns a provider specific error.

Enums holding this variant will never compare equal to each other.
