2 Checks for usage of unconstrained numeric literals which may cause default numeric fallback in type
5 Default numeric fallback means that if numeric types have not yet been bound to concrete
6 types at the end of type inference, then integer type is bound to `i32`, and similarly
7 floating type is bound to `f64`.
9 See [RFC0212](https://github.com/rust-lang/rfcs/blob/master/text/0212-restore-int-fallback.md) for more information about the fallback.
12 For those who are very careful about types, default numeric fallback
13 can be a pitfall that cause unexpected runtime behavior.
16 This lint can only be allowed at the function level or above.
