[][src]Struct xml::namespace::Namespace

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]

pub fn empty() -> Namespace[src]

Returns an empty namespace.

pub fn is_empty(&self) -> bool[src]

Checks whether this namespace is empty.

pub fn is_essentially_empty(&self) -> bool[src]

Checks whether this namespace is essentially empty, that is, it does not contain anything but default mappings.

pub fn contains<P: ?Sized + AsRef<str>>(&self, prefix: &P) -> bool[src]

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>, 
[src]

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>, 
[src]

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<'a, P: ?Sized + AsRef<str>>(&'a self, prefix: &P) -> Option<&'a str>[src]

Queries the namespace for the given prefix.

Parameters

  • prefix --- namespace prefix.

Return value

Namespace URI corresponding to the given prefix, if it is present.
