std::erase, std::erase_if (std::forward_list)
From cppreference.com
< cpp | container | forward list

| template< class T, class Alloc, class U > void erase(std::forward_list<T,Alloc>& c, const U& value); |
(1) | (since C++20) |
| template< class T, class Alloc, class Pred > void erase_if(std::forward_list<T,Alloc>& c, Pred pred); |
(2) | (since C++20) |
1) Erases all elements that compare equal to
value from the container. Equivalent to c.remove_if([&](auto& elem) { return elem == value; });2) Erases all elements that satisfy the predicate
pred from the container. Equivalent to c.remove_if(pred);Parameters
| c | - | container from which to erase |
| value | - | value to be removed |
| pred | - | unary predicate which returns true if the element should be erased. The expression pred(v) must be convertible to bool for every argument |
Complexity
Linear.

Notes
Unlike std::forward_list::remove, erase accepts heterogenous types and does not force a conversion to the container's value type before invoking the == operator.
