Expand description
Sans-IO implementation of SOCKS4 and SOCKS4a.
SOCKS4 is the classic, pre-RFC protocol: a single request/response
exchange over TCP with a NUL-terminated user identifier, supporting the
CONNECT and BIND commands. SOCKS4a extends it with a trailing domain
name so that DNS resolution can be deferred to the server - the direct
ancestor of the SOCKS5h mode.
As with crate::socks5, this module only encodes and decodes messages;
it does not impose a state machine on the caller.
Re-exports§
pub use messages::Request;pub use messages::Response;pub use types::Address;pub use types::CommandType;pub use types::Reply;
Modules§
- messages
- The SOCKS4 request/response pair, covering the SOCKS4a extension.
- types
- SOCKS4 wire types: the caret-encoded command and reply numbers and the
Addresstype shared by both messages.
Constants§
- REQUEST_
VERSION - The SOCKS4 protocol version byte (
VN) of client requests. - RESPONSE_
VERSION - The version byte (
VN) of SOCKS4 server responses; the classic protocol replies with a NUL here rather than with the request version.
