Struct xmltree::Namespace
[−]
[src]
pub struct Namespace(pub BTreeMap<String, String>);
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[src]
fn empty() -> Namespace
Returns an empty namespace.
fn is_empty(&self) -> bool
Checks whether this namespace is empty.
fn is_essentially_empty(&self) -> bool
Checks whether this namespace is essentially empty, that is, it does not contain anything but default mappings.
fn contains<P>(&self, prefix: &P) -> bool where 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.
fn put<P, U>(&mut self, prefix: P, uri: U) -> bool where 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.
fn force_put<P, U>(&mut self, prefix: P, uri: U) -> Option<String> where 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.
fn get<P>(&'a self, prefix: &P) -> Option<&'a str> where 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.
