# Clippy configuration (applies to every crate under this directory that
# does not have its own clippy.toml, including probes/clippy_canary).

# astro-float primitives that do not terminate or misbehave; the safe
# replacements live in `src/base/bigfloat.rs`, the only module allowed to
# call them (`#[allow(clippy::disallowed_methods)]`).  CI runs clippy on
# `probes/clippy_canary`, which calls each of them, and expects it to fail:
# if an astro-float release moves `BigFloat` so that a path below stops
# resolving, clippy silently stops linting it and the canary notices.
