encoded_fragment() const noexcept;
----

== Description


This function returns the fragment as a
string with percent-escapes.
Ownership is not transferred; the
string returned references the underlying
character buffer, which must remain valid
or else undefined behavior occurs.

=== Example
[,cpp]
----
assert( url_view( "http://www.example.com/index.htm#a%2D1" ).encoded_fragment() == "a%2D1" );
----

=== Complexity

Constant.

=== Exception Safety

Throws nothing.

=== BNF
[,cpp]
----
fragment        = *( pchar / "/" / "?" )

pchar           = unreserved / pct-encoded / sub-delims / ":" / "@"
----

=== Specification

* link:https://datatracker.ietf.org/doc/html/rfc3986#section-3.5[3.5. Fragment (rfc3986)]
