Struct NamespaceEntry

struct NamespaceEntry {
    start: usize,
    prefix_len: usize,
    value_len: usize,
    level: i32,
}

An entry that contains index into the buffer with namespace bindings.

Defines a mapping from namespace prefix to namespace name. If prefix is empty, defines a default namespace binding that applies to unprefixed element names (unprefixed attribute names do not bind to any namespace and they processing is dependent on the element in which their defined).

Fields

start: usize

Index of the namespace in the buffer

prefix_len: usize

Length of the prefix

• if greater than zero, then binds this namespace to the slice [start..start + prefix_len] in the buffer.
• else defines the current default namespace.

value_len: usize

The length of a namespace name (the URI) of this namespace declaration. Name started just after prefix and extend for value_len bytes.

The XML standard specifies that an empty namespace value ‘removes’ a namespace declaration for the extent of its scope. For prefix declarations that’s not very interesting, but it is vital for default namespace declarations. With xmlns="" you can revert back to the default behaviour of leaving unqualified element names unqualified.

level: i32

Level of nesting at which this namespace was declared. The declaring element is included, i.e., a declaration on the document root has level = 1. This is used to pop the namespace when the element gets closed.

Implementations

impl NamespaceEntry

fn prefix<'b>(&self, ns_buffer: &'b [u8]) -> Option<Prefix<'b>>

Get the namespace prefix, bound to this namespace declaration, or None, if this declaration is for default namespace (xmlns="...").

fn namespace<'ns>(&self, buffer: &'ns [u8]) -> ResolveResult<'ns>

Gets the namespace name (the URI) slice out of namespace buffer

Returns None if namespace for this prefix was explicitly removed from scope, using xmlns[:prefix]=""
