Adds `Guid::parse_str(&str) -> Result<Guid, RpcError>` to `crates/mxaccess-rpc/src/guid.rs` as the inverse of the existing `Display` impl. Accepts the canonical dashed-hex form, optionally braced (.NET `B` format), case-insensitive, and tolerant of bare 32-char hex without dashes. Single-pass char-by-char nibble accumulator avoids per-byte string allocation; applies the same byte-swap of groups 1-3 that the `Display` impl reads. Eight new tests cover round-trip against the existing `Display` fixture (`crates/mxaccess-rpc/src/guid.rs:111-119`, `b49f92f7-c748-4169-8eca-a0670b012746`), braces, uppercase, no-dashes, zero-GUID, too-short, too-long, and non-hex rejection. The five live-NMX examples (`connect-write-read`, `subscribe`, `recovery`, `multi-tag`, `secured-write`) lose their per-file 15-line `parse_guid` helpers in favour of the canonical implementation. `asb-subscribe` and `subscribe-buffered` are unaffected — they don't parse GUIDs. Test count delta: 524 → 532 (+8) Open followups touched: F17 resolved. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
mxaccess (Rust port)
Native Rust replacement for AVEVA / Wonderware MXAccess. See ../design/ for
the architectural specification, ../src/ for the .NET reference (the
executable spec), and ../CLAUDE.md for project-wide rules.
Status
M0 — Workspace skeleton. Stub types compile; nothing is implemented yet.
See ../design/60-roadmap.md for the M0–M6 milestone plan.
