rust-clippy

A collection of lints that give helpful tips to newbies and catch oversights.

Lints included in this crate:

• single_match: Warns when a match statement with a single nontrivial arm (i.e, where the other arm is _ => {}) is used, and recommends if let instead.
• box_vec: Warns on usage of Box<Vec<T>>
• dlist: Warns on usage of DList
• str_to_string: Warns on usage of str::to_string()
• toplevel_ref_arg: Warns when a function argument is declared ref (i.e. fn foo(ref x: u8), but not fn foo((ref x, ref y): (u8, u8))).
• eq_op: Warns on equal operands on both sides of a comparison or bitwise combination
• bad_bit_mask: Denies expressions of the form _ & mask == select that will only ever return true or false (because in the example select containing bits that mask doesn't have)

You can allow/warn/deny the whole set using the clippy lint group (#[allow(clippy)], etc)
