Part of #6991. Add functions that take a
key_bytes
parameter.Passing T for the key type is more flexible than having akey_bytes
parameter that is passed sizeof(KeyType). E.g. we can testT.name == 'string'
to see whether to clone a key. (This is easier to implement than making the wholemap
struct a generic type).I also hope later to implement taking the address of a generic function, so we can support V's==
operator for any types that support it. E.g.m.key_eq_fn = &key_eq<T>
.Generics are not allowed ATM in builtin.
