What is the currently recommended method for sorting values in a vector?
832
There are two ways of sorting in Rust: sort_by() function and sort() function. The sort_by() function sorts the vector according to the given key, an integer or string, while the sort() function sorts the vector according to its element's order.
A vector in C++ can be easily sorted in ascending order using the sort() function defined in the algorithm header file. The sort() function sorts a given data structure and does not return anything. The sorting takes place between the two passed iterators or positions.
You can sort a vector of custom objects using the C++ STL function std::sort. The sort function has an overloaded form that takes as arguments first, last, comparator. The first and last are iterators to first and last elements of the container.
Approach: The sort() function in C++ STL is able to sort vector of strings if and only if it contains single numeric character for example, { '1', ' '} but to sort numeric vector of string with multiple character for example, {'12', '56', '14' } one should write own comparator inside sort() function.
A mutable slice of elements with a total ordering has a sort method.
Because Vec<T> implements DerefMut<[T]>, you can call this method directly on a vector, so vector.sort() works.

To sort a vector v, in most cases v.sort() will be what you need.
If you want to apply a custom ordering rule, you can do that via v.sort_by(). That includes cases where you want to sort values that:
Ord (such as f64, most structs, etc);Ord, but you want to apply a specific non-standard ordering rule.Also note that sort() and sort_by() use a stable sorting algorithm (i.e., equal elements are not reordered). If you don't need a stable sort, you can use sort_unstable() / sort_unstable_by(), as those are generally a bit faster and use less memory.
