Example Dylint libraries

The example libraries are separated into the following three categories:

• general - significant concerns; may produce false positives
• supplementary - lesser concerns, but with a low false positive rate
• restriction - lesser or stylistic concerns; may produce false positives (similar to Clippy's "restriction" category)
• experimental - not ready for primetime yet (similar to Clippy's "nursery" category)
• testing - used only for testing purposes

General

Example	Description/check
abs_home_path	String literals that are absolute paths into the user's home directory
await_holding_span_guard	Span guards held while calling await inside an async function
basic_dead_store	A lint to find simple instances of dead stores in arrays
crate_wide_allow	#![allow(...)] used at the crate level
incorrect_matches_operation	Incorrect operators used with matches! macros
non_local_effect_before_error_return	Non-local effects before return of an error
non_thread_safe_call_in_test	Non-thread-safe function calls in tests
wrong_serialize_struct_arg	Calls to serialization methods with incorrect len arguments

Supplementary

Example	Description/check
commented_out_code	Code that has been commented out
escaping_doc_link	Doc comment links that escape their packages
inconsistent_struct_pattern	Struct patterns whose fields do not match their declared order
local_ref_cell	RefCell local variables
nonexistent_path_in_comment	Lint for nonexistent paths in comments
redundant_reference	Reference fields used only to read one copyable subfield
unnamed_constant	Unnamed constants, aka magic numbers
unnecessary_borrow_mut	Calls to RefCell::borrow_mut that could be RefCell::borrow
unnecessary_conversion_for_trait	Unnecessary trait-behavior-preserving calls

Restriction

Example	Description/check
assert_eq_arg_misordering	assert_eq!(actual, expected)
collapsible_unwrap	An unwrap that could be combined with an expect or unwrap using and_then
const_path_join	Joining of constant path components
env_literal	Environment variables referred to with string literals
inconsistent_qualification	Inconsistent qualification of module items
misleading_variable_name	Variables whose names suggest they have types other than the ones they have
question_mark_in_expression	The ? operator in expressions
ref_aware_redundant_closure_for_method_calls	A ref-aware fork of redundant_closure_for_method_calls
register_lints_warn	Calls to rustc_errors::DiagCtxtHandle::warn from within a register_lints function
suboptimal_pattern	Patterns that could perform additional destructuring
try_io_result	The ? operator applied to std::io::Result

Experimental

Example	Description/check
derive_opportunity	Traits that could be derived
missing_doc_comment_openai	A lint that suggests doc comments using OpenAI
overscoped_allow	allow attributes whose scope could be reduced

Testing

Example	Description/check
clippy	All of the Clippy lints as a Dylint library
straggler	A lint that uses an old toolchain for testing purposes

Notes

1. Each example is in its own workspace so that it can have its own rust-toolchain.
2. Each example is configured to use the installed copy of dylint-link. To use the copy within this repository, change the example's .cargo/config.toml file as follows:

   [target.x86_64-unknown-linux-gnu]
   linker = "../../../target/debug/dylint-link"
