# Clippy configuration for WaveFlow
# Applied when running: cargo clippy --manifest-path src-tauri/Cargo.toml --all-targets
#
# This file only controls numeric thresholds and feature-detection hints.
# Lint allow/warn/deny attributes belong in src-tauri/src/lib.rs (crate-wide)
# or inline with #[allow(...)] for justified local exceptions.

# ── Rust version hint ─────────────────────────────────────────────────────────
# Prevents Clippy from suggesting APIs not available before this version.
# Tauri 2 + sqlx 0.8 require ≥ 1.75; bumped to 1.80 for `std::sync::LazyLock`
# (used by the Last.fm HTML-stripper static regexes in `src/lastfm.rs`).
msrv = "1.80"

# ── Complexity thresholds ─────────────────────────────────────────────────────
# Tauri command handlers often receive many parameters (pool, state, options…).
too-many-arguments-threshold = 8

# Scanner, decoder, and DLNA Browse handlers are legitimately long.
too-many-lines-threshold = 150

# Allow moderately complex match arms in the audio engine and SQL builders.
cognitive-complexity-threshold = 30

# ── Type complexity ───────────────────────────────────────────────────────────
# sqlx query results and nested async combinators push this threshold.
type-complexity-threshold = 350

# ── Allowed identifier characters ─────────────────────────────────────────────
# Accept snake_case names that include common audio / signal-processing
# abbreviations (e.g. `pcm_buf`, `rms_db`, `bpm_f32`).
allowed-idents-below-min-chars = ["db", "id", "lp", "hp", "eq", "bpm", "rms", "fir"]
