std::size_t
erase(
    core::string_view key,
    ignore_case_param ic = = {}) noexcept;

This function removes an element from the container.

All iterators that are equal to `pos` or come after are invalidated.


url u( "?first=John&last=Doe" );

params_ref::iterator it = u.params().erase( u.params().begin() );

assert( u.encoded_query() == "last=Doe" );

An iterator to one past the removed element.

Name	Description
pos	An iterator to the element.
first,	last The range of elements to erase.
key	The key to match. By default, a case-sensitive comparison is used.
ic	An optional parameter. If the value ignore_case is passed here, the comparison is case-insensitive.
