rsx-cli Architecture

CLI tools for RSX exchange operations.

Commands

wal-dump

Reads WAL files via WalReader::open_from_seq() from rsx-cast. Iterates all records sequentially, printing sequence number, record type name, payload length, and CRC32C.

Uses clap for argument parsing. Recognizes all standard record types: FILL, BBO, ORDER_INSERTED, ORDER_CANCELLED, ORDER_DONE, CONFIG_APPLIED, CAUGHT_UP, ORDER_ACCEPTED, MARK_PRICE, ORDER_REQUEST, ORDER_RESPONSE, CANCEL_REQUEST, ORDER_FAILED.

Unknown record types are printed as UNKNOWN(N).

Architectural Decisions

Runtime: tokio. The CLI does sequential file I/O and occasional async work (Postgres queries, --follow polling on EOF). tokio is the boring choice and matches what the inspected components already use. There is no hot loop here and no latency budget — the CLI runs offline, not on the GW→ME→GW critical path. See ../notes/tiles.md for when tiles or monoio apply instead.
