url_base::set_fragment

Set the fragment.

Synopsis
url_base&
set_fragment(
    core::string_view s);
Description

This function sets the fragment to the specified string, which may be empty. An empty fragment is distinct from having no fragment. Reserved characters in the string are percent-escaped in the result.

Example
assert( [link url.ref.boost__urls__url_base.url `url`]( "?first=john&last=doe" ).[link url.ref.boost__urls__url_base.set_encoded_fragment `set_encoded_fragment`]( "john doe" ).[link url.ref.boost__urls__url_base.encoded_fragment `encoded_fragment`]() == "john%20doe" );
Postconditions
this->[link url.ref.boost__urls__url_base.has_fragment `has_fragment`]() == true && this->[link url.ref.boost__urls__url_base.fragment `fragment`]() == s
