Description

This function replaces the contents of the element at pos with the specified param.

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

The strings passed in must not come from the element being replaced, or else the behavior is undefined. 
url u( "?first=John&last=Doe" );

u.encoded_params().replace( u.encoded_params().begin(), { "title", "Mr" });

assert( u.encoded_query() == "title=Mr&last=Doe" );

Linear in this->url().encoded_query().size().

Strong guarantee.

Calls to allocate may throw. Exceptions thrown on invalid input.
