    FwdIt first,
    FwdIt last);

Description

This function replaces a range of segments with annother range of segments. Reserved characters in the new range are automatically escaped.

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

Preconditions

None of the character buffers referenced by the new range may overlap the character buffer of the underlying url, or else the behavior is undefined.

Complexity

Exception Safety

Strong guarantee. Calls to allocate may throw.

Return Value

An iterator to the first segment inserted, or one past to if init.size() == 0.
