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.

`ErrUnknownType`

ErrUnknownType indicates an error with Unknown info.

`ErrConnectionClosed`

ErrConnectionClosed indicates an operation executed after connection has already been closed.

`ErrDataChannelNotOpen`

ErrDataChannelNotOpen indicates an operation executed when the data channel is not (yet) open.

`ErrCertificateExpired`

ErrCertificateExpired indicates that an x509 certificate has expired.

`ErrNoTurnCredentials`

ErrNoTurnCredentials indicates that a TURN server URL was provided without required credentials.

`ErrTurnCredentials`

ErrTurnCredentials indicates that provided TURN credentials are partial or malformed.

`ErrExistingTrack`

ErrExistingTrack indicates that a track already exists.

`ErrPrivateKeyType`

ErrPrivateKeyType indicates that a particular private key encryption chosen to generate a certificate is not supported.

`ErrModifyingPeerIdentity`

ErrModifyingPeerIdentity indicates that an attempt to modify PeerIdentity was made after PeerConnection has been initialized.

`ErrModifyingCertificates`

ErrModifyingCertificates indicates that an attempt to modify Certificates was made after PeerConnection has been initialized.

`ErrNonCertificate`

ErrNonCertificate indicates that there is no certificate

`ErrModifyingBundlePolicy`

ErrModifyingBundlePolicy indicates that an attempt to modify BundlePolicy was made after PeerConnection has been initialized.

`ErrModifyingRTCPMuxPolicy`

ErrModifyingRTCPMuxPolicy indicates that an attempt to modify RTCPMuxPolicy was made after PeerConnection has been initialized.

`ErrModifyingICECandidatePoolSize`

ErrModifyingICECandidatePoolSize indicates that an attempt to modify ICECandidatePoolSize was made after PeerConnection has been initialized.

`ErrStringSizeLimit`

ErrStringSizeLimit indicates that the character size limit of string is exceeded. The limit is hardcoded to 65535 according to specifications.

`ErrMaxDataChannelID`

ErrMaxDataChannelID indicates that the maximum number ID that could be specified for a data channel has been exceeded.

`ErrNegotiatedWithoutID`

ErrNegotiatedWithoutID indicates that an attempt to create a data channel was made while setting the negotiated option to true without providing the negotiated channel ID.

`ErrRetransmitsOrPacketLifeTime`

ErrRetransmitsOrPacketLifeTime indicates that an attempt to create a data channel was made with both options max_packet_life_time and max_retransmits set together. Such configuration is not supported by the specification and is mutually exclusive.

`ErrCodecNotFound`

ErrCodecNotFound is returned when a codec search to the Media Engine fails

`ErrNoRemoteDescription`

ErrNoRemoteDescription indicates that an operation was rejected because the remote description is not set

`ErrIncorrectSDPSemantics`

ErrIncorrectSDPSemantics indicates that the PeerConnection was configured to generate SDP Answers with different SDP Semantics than the received Offer

`ErrIncorrectSignalingState`

ErrIncorrectSignalingState indicates that the signaling state of PeerConnection is not correct

`ErrProtocolTooLarge`

ErrProtocolTooLarge indicates that value given for a DataChannelInit protocol is longer then 65535 bytes

`ErrSenderNotCreatedByConnection`

ErrSenderNotCreatedByConnection indicates remove_track was called with a RtpSender not created by this PeerConnection

`ErrSenderInitialTrackIdAlreadySet`

ErrSenderInitialTrackIdAlreadySet indicates a second call to [RtpSender::set_initial_track_id] which is not allowed.

`ErrSessionDescriptionNoFingerprint`

ErrSessionDescriptionNoFingerprint indicates set_remote_description was called with a SessionDescription that has no fingerprint

`ErrSessionDescriptionInvalidFingerprint`

ErrSessionDescriptionInvalidFingerprint indicates set_remote_description was called with a SessionDescription that has an invalid fingerprint

`ErrSessionDescriptionConflictingFingerprints`

ErrSessionDescriptionConflictingFingerprints indicates set_remote_description was called with a SessionDescription that has an conflicting fingerprints

`ErrSessionDescriptionMissingIceUfrag`

ErrSessionDescriptionMissingIceUfrag indicates set_remote_description was called with a SessionDescription that is missing an ice-ufrag value

`ErrSessionDescriptionMissingIcePwd`

ErrSessionDescriptionMissingIcePwd indicates set_remote_description was called with a SessionDescription that is missing an ice-pwd value

`ErrSessionDescriptionConflictingIceUfrag`

ErrSessionDescriptionConflictingIceUfrag indicates set_remote_description was called with a SessionDescription that contains multiple conflicting ice-ufrag values

`ErrSessionDescriptionConflictingIcePwd`

ErrSessionDescriptionConflictingIcePwd indicates set_remote_description was called with a SessionDescription that contains multiple conflicting ice-pwd values

`ErrNoSRTPProtectionProfile`

ErrNoSRTPProtectionProfile indicates that the DTLS handshake completed and no SRTP Protection Profile was chosen

`ErrFailedToGenerateCertificateFingerprint`

ErrFailedToGenerateCertificateFingerprint indicates that we failed to generate the fingerprint used for comparing certificates

`ErrNoCodecsAvailable`

ErrNoCodecsAvailable indicates that operation isn’t possible because the MediaEngine has no codecs available

`ErrUnsupportedCodec`

ErrUnsupportedCodec indicates the remote peer doesn’t support the requested codec

`ErrSenderWithNoCodecs`

ErrSenderWithNoCodecs indicates that a RTPSender was created without any codecs. To send media the MediaEngine needs at least one configured codec.

`ErrRTPSenderNewTrackHasIncorrectKind`

ErrRTPSenderNewTrackHasIncorrectKind indicates that the new track is of a different kind than the previous/original

`ErrUnbindFailed`

ErrUnbindFailed indicates that a TrackLocal was not able to be unbind

`ErrNoPayloaderForCodec`

ErrNoPayloaderForCodec indicates that the requested codec does not have a payloader

`ErrRegisterHeaderExtensionInvalidDirection`

ErrRegisterHeaderExtensionInvalidDirection indicates that a extension was registered with a direction besides sendonly or recvonly

`ErrRegisterHeaderExtensionNoFreeID`

ErrRegisterHeaderExtensionNoFreeID indicates that there was no extension ID available which in turn means that all 15 available id(1 through 14) have been used.

`ErrSimulcastProbeOverflow`

ErrSimulcastProbeOverflow indicates that too many Simulcast probe streams are in flight and the requested SSRC was ignored

`ErrDetachNotEnabled`

`ErrDetachBeforeOpened`

`ErrDtlsTransportNotStarted`

`ErrDtlsKeyExtractionFailed`

`ErrFailedToStartSRTP`
