Description

I have a long list of lints in Cargo.toml. But moving them to clippy.toml deactivates them. Would be nice to have it moved into clippy.toml which I place inside .cargo folder (along with other configs like deny.toml, audit.toml, rustfmt.toml) to keep the Cargo.toml file clean and focused on dependencies.

Here is my clippy config in Cargo.toml:

[lints.clippy] let_and_return = "allow" similar_names = "allow" too_many_arguments = "allow" missing_errors_doc = "allow" pub_with_shorthand = "allow" missing_docs_in_private_items = "allow" field_scoped_visibility_modifiers = "allow" arbitrary_source_item_ordering = "warn" self_named_module_files = "allow" single_char_lifetime_names = "allow" single_call_fn = "allow" allow_attributes_without_reason = "allow" unused_trait_names = "allow" blanket_clippy_restriction_lints = "allow" allow_attributes = "allow" decimal_literal_representation = "allow" implicit_return = "allow" question_mark_used = "allow" multiple_inherent_impl = "allow" needless_pass_by_ref_mut = "warn" shadow_reuse = "warn" shadow_unrelated = "allow" pattern_type_mismatch = "allow" clone_on_ref_ptr = "allow" print_stdout = "allow" std_instead_of_core = "allow" std_instead_of_alloc = "allow" missing_inline_in_public_items = "allow" integer_division_remainder_used = "allow" absolute_paths = "allow" exit = "allow" arithmetic_side_effects = "allow" string_to_string = "warn" infinite_loop = "allow" wildcard_enum_match_arm = "allow" str_to_string = "warn" let_underscore_must_use = "warn" unwrap_used = "allow" as_conversions = "warn" default_numeric_fallback = "allow" else_if_without_else = "allow" min_ident_chars = "warn" separated_literal_suffix = "allow" unseparated_literal_suffix = "warn" verbose_file_reads = "allow" needless_raw_strings = "warn" missing_trait_methods = "allow" integer_division = "allow" empty_structs_with_brackets = "warn" unneeded_field_pattern = "warn" renamed_function_params = "allow" indexing_slicing = "warn" print_stderr = "allow" use_debug = "allow" let_underscore_untyped = "warn" unreachable = "warn" string_add = "allow" big_endian_bytes = "allow" float_arithmetic = "allow" semicolon_outside_block = "allow" panic_in_result_fn = "warn" map_with_unused_argument_over_ranges = "warn" iter_over_hash_type = "allow" redundant_type_annotations = "warn" shadow_same = "warn" get_unwrap = "warn" non_ascii_literal = "allow" if_then_some_else_none = "warn" undocumented_unsafe_blocks = "allow" panic = "allow" pathbuf_init_then_push = "warn" modulo_arithmetic = "allow" string_slice = "allow" redundant_pub_crate = "allow" option_if_let_else = "allow" use_self = "warn" missing_const_for_fn = "warn" significant_drop_tightening = "warn" iter_on_single_items = "allow" or_fun_call = "warn" redundant_clone = "warn" branches_sharing_code = "warn" tuple_array_conversions = "allow" literal_string_with_formatting_args = "warn" case_sensitive_file_extension_comparisons = "allow" pedantic = { level = "warn", priority = -1 } restriction = { level = "warn", priority = -1 } nursery = { level = "warn", priority = -1 }
