Extract the T-generic client session from fast-socks5 v1.0.0's
client.rs into src/vendor/client.rs (ADR-011 §Amendment extraction,
vendor.md cut table row 2): Socks5Stream<S> with use_stream (the
greeting, method-choice read, password sub-handshake, request
encoder, reply reader, socket accessors), the AsyncRead/AsyncWrite
impls, and the pruned Config (skip_auth only).
- typed MissingTargetAddr variant replaces upstream's
anyhow::Error::msg(...).into() at client.rs:285 (the one SocksError
addition; the client.rs:528 Other(anyhow!) site went with the cut
Socks5Datagram)
- use_password_auth's unreachable!() is an error return (upstream's
None-arm message; convention 2), and the sub-negotiation reply's
version byte is now checked (was only a dropped debug!)
- write -> write_all in request_header (clippy unused_io_amount;
byte-identical on a healthy stream)
- cut (not copied): Socks5Datagram, the Socks5Stream<TcpStream>
convenience impl (connect*/connect_raw), Config::connect_timeout
- 14 first-party duplex tests vs raw-byte mock servers (uncorrelated
from the vendored server typestate): both handshakes, 0xff
refusal, version mismatch, domain/IP request forms, the full
failure-code table, UDP-ASSOCIATE zero fallback, skip_auth,
io-impl copy, socket accessors
- mod.rs: doc touch-ups (client module now landed; fixed the
pre-existing broken intra-doc link)
Verification: cargo test (37 pass), --all-features, clippy
--all-targets -D warnings (native + wasm32), cargo check --target
wasm32-unknown-unknown, cargo fmt --check, cargo doc --no-deps.
The inline vendor (vendor.md, ADR-011 §Amendment) is the root of the
crate's dependency graph; this decomposes it before any downstream
group (params/wire/producer/consumer/doors).
- vendor-crate-scaffolding: Cargo.toml (wasm-clean tokio subset, no
alkcall yet), lib.rs, vendor/ skeleton, bundled MIT notice
- vendor-wire-vocabulary: consts, codecs, errors, macros — with the
extraction-boundary pins (error-variant pruning, pub command
codecs, macro de-exporting)
- vendor-server-typestate: Socks5ServerProtocol + the new_reply
publication (carried change #2); BIND's driving is producer-group
work, the vendor carries only the surface
- vendor-client-session: Socks5Stream::use_stream path + the
AsyncRead/AsyncWrite impls; Config pruned (connect_timeout cut);
tests against a raw-byte mock server so it runs parallel with the
typestate task
- vendor-differential-tests: RFC edge-case suite over duplex streams,
pinning upstream behavior per vendor.md's differential posture
- review-vendor-extraction: the gate before downstream groups —
file-by-file diff vs /workspace/fast-socks5 must contain only
cut/carried-change/adjustment hunks
Graph validated: all dependency ids resolve, no cycles; topological
order scaffolding → wire → (typestate ∥ client) → tests → review.
