Enum url::Position
[−]
[src]
pub enum Position { BeforeScheme, AfterScheme, BeforeUsername, AfterUsername, BeforePassword, AfterPassword, BeforeHost, AfterHost, BeforePort, AfterPort, BeforePath, AfterPath, BeforeQuery, AfterQuery, BeforeFragment, AfterFragment, }
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..]
.
