Enum xrust::item::Item[−][src]

pub enum Item<'a> {
    Node(RcNode<NodeDefn>),
    XNode(Node<'a, 'a>),
    JsonValue(JsonValue),
    Function,
    Value(Value),
}

Expand description

An Item in a Sequence. Can be a Node, Function or Value.

Nodes are implemented directly, using either trees, roxmltree or JsonValue crates.

In the future it is planned to implement Nodes using a Trait.

Functions are not yet implemented.

Variants

Node(RcNode<NodeDefn>)

A trees-based Node

XNode(Node<'a, 'a>)

A roxmltree-based Node

JsonValue(JsonValue)

A JsonValue-based Node

Function

Functions are not yet supported

Value(Value)

A scalar value

Implementations

impl<'a> Item<'a>[src]

pub fn to_string(&self) -> String[src]

Gives the string value of an item. All items have a string value.

pub fn to_xml(&self) -> String[src]

Serialize as XML

pub fn to_json(&self) -> String[src]

Serialize as JSON

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

Determine the effective boolean value of the item. See XPath 2.4.3.

pub fn to_int(&self) -> Result<i64, Error>[src]

Gives the integer value of the item, if possible.

pub fn to_double(&self) -> f64[src]

Gives the double value of the item. Returns NaN if the value cannot be converted to a double.

pub fn to_name(&self) -> &str[src]

Gives the name of the item. Certain types of Nodes have names, such as element-type nodes. If the item does not have a name returns an empty string.

pub fn compare(&self, other: &Item<'_>, op: Operator) -> Result<bool, Error>[src]

Compare two items.

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

Is this item an element-type node?
