- prettytable-rs: Force cast a &Vec<T> to &[T] may lead to undefined behavior
- Details
-
In function
Table::as_ref, a reference of vector is force cast to slice. There are multiple problems here: 1. To guarantee the size is correct, we have to first doVec::shrink_to_fit. The function requires a mutable reference, so we have to force cast from immutable to mutable, which is undefined behavior (UB). 2. Even if (1) is sound,&Vec<T>and&[T]still might not have the same layout. Treating them equally may lead to undefinted behavior (UB). - Database specific
