Expand description

Indicates a position within a URL based on its components.

A range of positions can be used for slicing Url:

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 (so that &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.) For example, &url[..BeforeFragment] would include a # delimiter (if present in url), so &url[..AfterQuery] might be desired instead.

BeforeScheme and AfterFragment are always the start and end of the entire URL, so &url[BeforeScheme..X] is the same as &url[..X] and &url[X..AfterFragment] is the same as &url[X..].
