Constructor

== Synopsis

Declared in `<https://www.github.com/boostorg/url/blob/develop/include/boost/url/segments_view.hpp#L211[boost/url/segments_view.hpp]>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
segments_view(
    xref:boost/urls/segments_base/iterator.adoc[iterator] first,
    xref:boost/urls/segments_base/iterator.adoc[iterator] last) noexcept;
----

== Description

This function creates a new xref:boost/urls/segments_view/2constructor-0c9.adoc[`segments_view`] from a pair of iterators referring to elements of another segments view. The resulting view references the same underlying character buffer as the original.

The caller is responsible for ensuring that the lifetime of the original buffer extends until the constructed view is no longer referenced.

== Example

[,cpp]
----
segments_view ps( "/path/to/file.txt" );

segments_view sub(
    std::next(ps.begin()),
    ps.end());

// sub represents "to/file.txt"
----
== Preconditions

The iterators must be valid and belong to the same xref:boost/urls/segments_view/2constructor-0c9.adoc[`segments_view`].

== Postconditions

`sub.buffer()` references characters in the original `ps.buffer()`.

== Complexity

Linear in `sub.buffer()`

== Exception Safety

Throws nothing.

== Parameters
