// Copyright Valkey GLIDE Project Contributors - SPDX Identifier: Apache-2.0
//! GLIDE's command API: [`AsyncCommands`] and [`Commands`], and their typed
//! counterparts [`AsyncTypedCommands`] and [`TypedCommands`].
//!
//! One command table (below) defines all four traits via the
//! `implement_commands!` macro. Entries are source-compatible with
//! redis-rs's command table: same method names, generic parameter
//! order, bounds, and argument lists, so migrated call sites (including
//! turbofish annotations) compile unchanged.
//!
//! Each entry carries the command body (mirroring redis-rs's
//! `implement_commands!`), so the wire encoding matches redis-rs's
//! (except for the deliberate differences pinned in `differences.json` (e.g.
//! `hset_multiple` sends `HSET`, not `HMSET`); signature parity is enforced by
//! the `parity_tests` module (`src/parity_tests/`).
//!
//! The built command is handed to glide-core **by value** — the same
//! zero-extra-copy path as the rest of the client. Methods take `&self` (the clients are cheaply
//! cloneable handles); migrated `&mut` call sites still compile via
//! auto-borrow.
//!
//! Two deliberate deviations trade redis-rs parity for performance and
//! clarity (parity here is a command-surface contract, not a
//! connection-plumbing one):
//! * the traits are **not** coupled to the `redis` crate's connection-object
//!   (`ConnectionLike`) machinery — dispatch is GLIDE's owned-send path only;
//! * the `scan*` methods take `&self` and return GLIDE's own iterators
//!   ([`crate::commands::scan`]) with the familiar `next_item()` /
//!   `Iterator` shape, each page dispatched by value (no per-page copies).
//!
//! Commands beyond this table (the remaining stream commands, geo search,
//! `JSON.*`, …) live in the per-family extension traits in [`crate::commands`].
//!
//! Maintenance: add or adjust entries in the `implement_commands!`
//! invocation at the bottom of this file; the parity test will flag any
//! divergence from redis-rs's command table (see DEVELOPER.md).
