# =============================================================================
# NEOTH — clippy configuration
# Applied via: cargo clippy --all-targets --all-features -- -D warnings
# Reference: https://rust-lang.github.io/rust-clippy/master/
# =============================================================================

# Minimum Supported Rust Version — clippy uses this to suppress lints for
# features not available on the MSRV.
msrv = "1.91"

# Function argument count before clippy warns
too-many-arguments-threshold = 8

# Cognitive complexity score before clippy warns (cyclomatic-ish)
cognitive-complexity-threshold = 25

# Type complexity before clippy warns (nested generics count)
type-complexity-threshold = 250

# Allow up to 3 boolean function parameters before warning.
# Note: clippy 1.95 only ships `too-many-arguments-threshold`; the bool-
# parameter variant is unstable / nightly-only. Removed to keep stable
# `cargo clippy -- -D warnings` from rejecting the config.

# Suppress: tab characters in doc comments (used in ASCII art / tables)
# Lint name: clippy::tabs_in_doc_comments — suppressed project-wide here.
# Individual suppressions: #[allow(clippy::tabs_in_doc_comments)]
# Note: rustfmt.toml uses spaces, but doc-comment tables sometimes use tabs.
# This is a stylistic preference, not a correctness issue.
# The suppress is done via .cargo/config.toml or RUSTFLAGS in CI; clippy.toml
# does not directly support lint-level overrides — use allow attributes inline.

# Vec<T> length before suggesting Box<[T]>
vec-box-size-threshold = 4096

# Minimum number of variants before suggesting non-exhaustive
enum-variant-size-threshold = 200

# `large-stack-arrays-threshold` is also nightly-only in clippy 1.95.
# Remove until the stable channel ships it; the default behaviour is fine
# for v0.1.x (the buffer in healthz.rs is 8 KiB, far below stack limits).
