boost::urls::segments_ref::insert

Insert segments

Synopsis

Declared in <include/boost/url/segments_ref.hpp>

iterator
insert(
    iterator before,
    std::initializer_list<core::string_view> init);

Description

This function inserts the segments in an initializer list before the specified position. Reserved characters in the list are percent-escaped in the result.

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

NOTE

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

url u( "/file.txt" ); u.segments().insert( u.segments().begin(), { "path", "to" } );

Linear in `init.size() + this->url().encoded_resource().size()`.

Strong guarantee.

Calls to allocate may throw.

Return Value

An iterator to the first element inserted, or `before` if `init.size() == 0`.

Parameters

Name Description
before

An iterator before which the list is inserted. This may be equal to `end()`.

init

The list of segments to insert.
