static_url::set_encoded_fragment

Set the fragment.

Synopsis
static_url&
set_encoded_fragment(
    pct_string_view s);
Description

This function sets the fragment to the specified string, which may contain percent-escapes and which may be empty. An empty fragment is distinct from having no fragment. Escapes in the string are preserved, and reserved characters in the string are percent-escaped in the result.

Example
assert( url( "?first=john&last=doe" ).[link url.ref.boost__urls__static_url.set_encoded_fragment `set_encoded_fragment`]( "john%2Ddoe" ).[link url.ref.boost__urls__static_url.fragment `fragment`]() == "john-doe" );
Postconditions
this->[link url.ref.boost__urls__static_url.has_fragment `has_fragment`]() == true && this->[link url.ref.boost__urls__static_url.fragment `fragment`]() == decode_view( s )
Complexity

Linear in this->size() + s.size().

Exception Safety

Strong guarantee. Calls to allocate may throw. Exceptions thrown on invalid input.

Exceptions
