This opaque type represent a connection to a destination.

return a simple tuple of the port and hostname that we're connected to.

Connection Parameters to establish a Connection.

The strict minimum is an hostname and the port.

If you need to establish a TLS connection, you should make sure connectionUseSecure is correctly set.

If you need to connect through a SOCKS, you should make sure connectionUseSocks is correctly set.

TLS Settings that can be either expressed as simple settings, or as full blown TLS.Params settings.

Unless you need access to parameters that are not accessible through the simple settings, you should use TLSSettingsSimple.

Proxy settings for the connection.

OtherProxy handles specific application-level proxies like HTTP proxies.

The simple SOCKS settings is just the hostname and portnumber of the SOCKS proxy server.

That's for now the only settings in the SOCKS package, socks password, or any sort of other authentications is not yet implemented.

This is the exception raised if we reached the user specified limit for the line in ConnectionGetLine.

Exception raised when there's no resolution for a specific host

Exception raised when the connect failed

Initialize the library with shared parameters between connection.

Shared values (certificate store, sessions, ..) between connections

At the moment, this is only strictly needed to shared sessions and certificates when using a TLS enabled connection.

Use an already established handle to create a connection object.

if the TLS Settings is set, it will do the handshake with the server. The SOCKS settings have no impact here, as the handle is already established

connect to a destination using the parameter

Close a connection.

Get some bytes from a connection.

The size argument is just the maximum that could be returned to the user. The call will return as soon as there's data, even if there's less than requested. Hence, it behaves like hGetSome.

On end of input, connectionGet returns 0, but subsequent calls will throw an isEOFError exception.

Get exact count of bytes from a connection.

The size argument is the exact amount that must be returned to the user. The call will wait until all data is available. Hence, it behaves like hGet.

On end of input, connectionGetExact will throw an isEOFError exception.

Get the next block of data from the connection.

Like connectionGetChunk, but return the unused portion to the buffer, where it will be the next chunk read.

Get the next line, using ASCII LF as the line terminator.

This throws an isEOFError exception on end of input, and LineTooLong when the number of bytes gathered is over the limit without a line terminator.

The actual line returned can be bigger than the limit specified, provided that the last chunk returned by the underlaying backend contains a LF. In another world only when we need more input and limit is reached that the LineTooLong exception will be raised.

An end of file will be considered as a line terminator too, if line is not empty.

Put a block of data in the connection.

Activate secure layer using the parameters specified.

This is typically used to negociate a TLS channel on an already establish channel, e.g. supporting a STARTTLS command. it also flush the received buffer to prevent application confusing received data before and after the setSecure call.

If the connection is already using TLS, nothing else happens.

Returns if the connection is establish securely or not.
