Clippy lint configuration

## Fields§

§`arithmetic_side_effects_allowed: FxHashSet<String>`

Lint: ARITHMETIC_SIDE_EFFECTS.

Suppress checking of the passed type names in all types of operations.

If a specific operation is desired, consider using `arithmetic_side_effects_allowed_binary` or `arithmetic_side_effects_allowed_unary` instead.

###### §Example

    arithmetic-side-effects-allowed = ["SomeType", "AnotherType"]

###### §Noteworthy

A type, say `SomeType`, listed in this configuration has the same behavior of `["SomeType" , "*"], ["*", "SomeType"]` in `arithmetic_side_effects_allowed_binary`.

§`arithmetic_side_effects_allowed_binary: Vec<[String; 2]>`

Lint: ARITHMETIC_SIDE_EFFECTS.

Suppress checking of the passed type pair names in binary operations like addition or multiplication.

Supports the “*” wildcard to indicate that a certain type won’t trigger the lint regardless of the involved counterpart. For example, `["SomeType", "*"]` or `["*", "AnotherType"]`.

Pairs are asymmetric, which means that `["SomeType", "AnotherType"]` is not the same as `["AnotherType", "SomeType"]`.

###### §Example

    arithmetic-side-effects-allowed-binary = [["SomeType" , "f32"], ["AnotherType", "*"]]

§`arithmetic_side_effects_allowed_unary: FxHashSet<String>`

Lint: ARITHMETIC_SIDE_EFFECTS.

Suppress checking of the passed type names in unary operations like “negation” (`-`).

###### §Example

    arithmetic-side-effects-allowed-unary = ["SomeType", "AnotherType"]

§`avoid_breaking_exported_api: bool`

Lint: ENUM_VARIANT_NAMES, LARGE_TYPES_PASSED_BY_VALUE, TRIVIALLY_COPY_PASS_BY_REF, UNNECESSARY_WRAPS, UNUSED_SELF, UPPER_CASE_ACRONYMS, WRONG_SELF_CONVENTION, BOX_COLLECTION, REDUNDANT_ALLOCATION, RC_BUFFER, VEC_BOX, OPTION_OPTION, LINKEDLIST, RC_MUTEX, UNNECESSARY_BOX_RETURNS, SINGLE_CALL_FN, NEEDLESS_PASS_BY_REF_MUT.

Lint: DISALLOWED_NAMES.
