Function url:: set_path

Set the path.

Synopsis

            url&
set_path(core::string_view s);

Description

This function sets the path to the string, which may be empty. Reserved characters in the string are percent-escaped in the result.

NOTE

The library may adjust the final result to ensure that no other parts of the url is semantically affected.

NOTE

This function does not encode '/' chars, which are unreserved for paths but reserved for path segments. If a path segment should include encoded '/'s to differentiate it from path separators, the functions set_encoded_path or segments should be used instead.

Example


url u( "http://www.example.com" );

u.set_path( "path/to/file.txt" );

assert( u.path() == "/path/to/file.txt" );

Complexity

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

Exception Safety

Strong guarantee. Calls to allocate may throw.

BNF


path          = path-abempty    ; begins with "/" or is empty
              / path-absolute   ; begins with "/" but not "//"
              / path-noscheme   ; begins with a non-colon segment
              / path-rootless   ; begins with a segment
              / path-empty      ; zero characters

path-abempty  = *( "/" segment )
path-absolute = "/" [ segment-nz *( "/" segment ) ]
path-noscheme = segment-nz-nc *( "/" segment )
path-rootless = segment-nz *( "/" segment )
path-empty    = 0
