boost::urls::segments_ref::replace

Synopsis

template<class FwdIt>
iterator
replace(
    iterator from,
    iterator to,
    FwdIt first,
    FwdIt last);

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.

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.

Linear in std::distance( first, last ) + this->url().encoded_resouce().size().

Strong guarantee. Calls to allocate may throw.

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

Name	Description
from	The beginning of the range of segments to replace.
to	The end of the range of segments to replace.
first	The beginning of the range of segments to assign.
last	The end of the range of segments to assign.
