From cppreference.com
Defined in header <list>

||
template< class T, class Alloc, class U > void erase(std::list<T,Alloc>& c, const U& value); |
(1) | (since C++20) |
template< class T, class Alloc, class Pred > void erase_if(std::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::list::remove, erase
accepts heterogenous types and does not force a conversion to the container's value type before invoking the == operator.
