[−]Struct xmltree::Namespace
Namespace is a map from prefixes to namespace URIs.
No prefix (i.e. default namespace) is designated by NS_NO_PREFIX
constant.
Methods
impl Namespace
pub fn empty() -> Namespace
Returns an empty namespace.
pub fn is_empty(&self) -> bool
Checks whether this namespace is empty.
pub fn is_essentially_empty(&self) -> bool
Checks whether this namespace is essentially empty, that is, it does not contain anything but default mappings.
pub fn contains<P>(&self, prefix: &P) -> bool where
P: AsRef<str> + ?Sized,
P: AsRef<str> + ?Sized,
Checks whether this namespace mapping contains the given prefix.
Parameters
prefix
--- namespace prefix.
Return value
true
if this namespace contains the given prefix, false
otherwise.
pub fn put<P, U>(&mut self, prefix: P, uri: U) -> bool where
P: Into<String>,
U: Into<String>,
P: Into<String>,
U: Into<String>,
Puts a mapping into this namespace.
This method does not override any already existing mappings.
Returns a boolean flag indicating whether the map already contained the given prefix.
Parameters
prefix
--- namespace prefix;uri
--- namespace URI.
Return value
true
if prefix
has been inserted successfully; false
if the prefix
was already present in the namespace.
pub fn force_put<P, U>(&mut self, prefix: P, uri: U) -> Option<String> where
P: Into<String>,
U: Into<String>,
P: Into<String>,
U: Into<String>,
Puts a mapping into this namespace forcefully.
This method, unlike put()
, does replace an already existing mapping.
Returns previous URI which was assigned to the given prefix, if it is present.
Parameters
prefix
--- namespace prefix;uri
--- namespace URI.
Return value
Some(uri)
with uri
being a previous URI assigned to the prefix
, or
None
if such prefix was not present in the namespace before.
pub fn get<P>(&'a self, prefix: &P) -> Option<&'a str> where
P: AsRef<str> + ?Sized,
P: AsRef<str> + ?Sized,
Queries the namespace for the given prefix.
Parameters
prefix
--- namespace prefix.
Return value
Namespace URI corresponding to the given prefix, if it is present.
