Struct StreamParameters 

Source 
pub struct StreamParameters { /* private fields */ }
Expand description

A set of preferences used to declare how a new stream should be opened.

Implementations§

Source§

impl StreamParameters

Source

pub fn new() -> Self

Create a new StreamParameters using default settings.

Source

pub fn suppress_begin_flags(&mut self) -> &mut Self

Configure this StreamParameters to include no flags in any BEGIN message it generates.

This is used to implement onion services. It may make other operations inoperable.

Source

pub fn suppress_hostname(&mut self) -> &mut Self

Configure this StreamParameters to suppress hostnames in the BEGIN messages.

This is used to implement onion services. It will make other kinds of connections not work.

Source

pub fn ip_version(&mut self, preference: IpVersionPreference) -> &mut Self

Configure which IP version (IPv4 or IPv6) you’d like to request, if you’re connecting to a hostname.

The default is to allow either version, but to prefer IPv4.

Source

pub fn optimistic(&mut self, optimistic: bool) -> &mut Self

Configure whether the stream should be opened “optimistically.”

By default, streams are not “optimistic”. When you call ClientCirc::begin_stream(), the function won’t give you a stream until the exit node has confirmed that it has successfully opened a connection to your target address. It’s safer to wait in this way, but it is slower: it takes an entire round trip to get your confirmation.

If a stream is configured to be “optimistic”, then ClientCirc::begin_stream() will return the stream immediately, without waiting for an answer from the exit. You can start sending data on the stream right away, though of course this data will be lost if the connection is not actually successful.
