Close closes the Conn, performing necessary cleanup.

Write writes data to the Conn's IoInc handle if the connection is alive. It returns an error if the connection is closed.

Close closes a Client object. This will kill the datagram receiver loop, and any active stream objects.

releaseDatagramID releases a datagram flow ID back into the pool for use.

Sid returns the unique stream ID of the Conn.

Read reads data from the Conn's IoOut handle if the connection is alive. It returns an error if the connection is closed.

CreateTCPStream creates a TCP stream to the given address using the client. This function should ONLY be called after successfully calling ConnectToPr

ConnectToProxy connects the Client to the proxy.

CreateUDPStream creates a UDP stream to the given address using the client. This function should ONLY be called after calling |ConnectToProxy| succes

HandleConnectMasque creates a new TCP or UDP stream via the relayClient and returns the connected stream upon success.

IsDisallowedPort returns true if the given destination port number is a value that will be rejected by Fastly.

NewClient creates a new Client instance with the provided parameters.

NewClient provides a method that returns a new Client object, creating a new http3.RoundTripper object dedicated to be used with the provided proxy ad

Read reads from a datagram stream. Blocks if no data is available. If the provided []byte slice is not large enough for the message, it will be trunca

TLSVerifyFunc takes a cert data byte slice and returns a function that can be passed to the tls.Config.VerifyPeerCertificate for pinning.

Transfer copies data from src to dst and closes both when done.

handleConnectMasque handles a CONNECT request to the proxy and returns the connected stream upon success.

makeNewH2ClientConn must be called while c.mu is held.

makeTLSDialerContext makes a context for the TLS dialer. It checks if the context expires before a TLS connection is complete, and returns an error if

CreateTCPStream creates a TCP Stream through the proxy to the designated destination. Note that destAddr is in ip:port format, where ip CANNOT be a DN

CreateUDPStream creates a UDP Stream through the proxy Also starts the receiver loop for datagrams if it hasn't already been started. Returns a Datagr

StreamDataToDatagramChunk converts UDP payload data to a CONNECT-UDP datagram chunk. This protocol is for tunneling a UDP stream via an HTTP proxy ser

Write writes to a datagram stream. May block if the stream buffer is full. Note that this function requires prepending 1 to 9 bytes to send the datagr

datagramChunkToStreamData converts an encoded datagram chunk into a UDP raw byte slice. The input parameters are the CONNECT-UDP datagram chunk (chunk

datagramReceiveLoop pulls datagrams from the quic.Connection object and places them inside of the correct DatagramStream. It performs parsing of the i

decodeLoopUDP decodes data received from the proxied UDP stream. |udp.transport| should be the TLS connection's reader from proxy. |dst| should be the

Assemble the default port list using the global + constant values defined above. This returns a TCP and UDP port list.

dialProxyViaH2 returns a H2 transport struct with TLS settings. Note: the H2 transport handles the networking operations internally. |prot| is called

dialProxyViaTLSOnce returns a TCP connection with TLS. |prot| is called before connecting if not nil.

encodeLoopUDP encodes data and sends it to the proxied UDP stream. |udp.transport| should be the TLS connection's reader from proxy. |src| should be t

getNewDatagramID gets a new H3_DATAGRAM Flow ID to be used with a UDP stream.

loadPortFile loads the provided port file. It returns a list of TCP and UDP ports to forward. The format of the file is tcp:port_number or udp:port_n

sanitizeOptionsWithDefaults sets the default values for ProxyOptions.

startReceiveLoop starts datagramReceiveLoop with a given quic.Connection, first checking if it already has been started.

Close closes a DatagramStream, returning its flow ID to the pool by calling its closeTrigger().

Starts running the preproxy on localaddr by tunneling connections thru the given proxyaddr to the final destination targetServer for the ports configu
