Indicates a position within a URL based on its components.
A range of positions can be used for slicing
let serialization: &str = &some_url[..]; let serialization_without_fragment: &str = &some_url[..Position::AfterQuery]; let authority: &str = &some_url[Position::BeforeUsername..Position::AfterPort]; let data_url_payload: &str = &some_url[Position::BeforePath..Position::AfterQuery]; let scheme_relative: &str = &some_url[Position::BeforeUsername..];
In a pseudo-grammar (where
]? makes a sub-sequence optional),
URL components and delimiters that separate them are:
url = scheme ":" [ "//" [ username [ ":" password ]? "@" ]? host [ ":" port ]? ]? path [ "?" query ]? [ "#" fragment ]?
When a given component is not present,
its "before" and "after" position are the same
&some_url[BeforeFoo..AfterFoo] is the empty string)
and component ordering is preserved
(so that a missing query "is between" a path and a fragment).
The end of a component and the start of the next are either the same or separate
by a delimiter.
(Not that the initial
/ of a path is considered part of the path here, not a delimiter.)
&url[..BeforeFragment] would include a
# delimiter (if present in
&url[..AfterQuery] might be desired instead.
AfterFragment are always the start and end of the entire URL,
&url[BeforeScheme..X] is the same as
&url[X..AfterFragment] is the same as
