On the "safety" of escape_into.

[sirkon]

I am talking about

pub fn escape_into(value: &str, dst: &mut Vec<u8>) {

This thing is pure unsafe semantically, a clear UB. IMO it should be deprecated and an alternative should be recommended:

pub unsafe fn escape_append(value: &str, dst: *mut u8, len: usize) -> usize { // or *mut u8

This would be

• Fair. One should not promise what he's not going to deliver.
• Performant and actually more handy.
