Trait svgdom::ElementType[−][src]

pub trait ElementType {
    fn is_referenced(&self) -> bool;
    fn is_basic_shape(&self) -> bool;
    fn is_shape(&self) -> bool;
    fn is_container(&self) -> bool;
    fn is_text_content(&self) -> bool;
    fn is_text_content_child(&self) -> bool;
    fn is_graphic(&self) -> bool;
    fn is_gradient(&self) -> bool;
    fn is_paint_server(&self) -> bool;
}

This trait contains methods that check element's type according to the SVG spec.

Note that all methods works with Node type and will return false if node's type is not equal to NodeType::Element.

Panics

All methods panics if the node is currently mutability borrowed.

Required Methods

`fn is_referenced(&self) -> bool`

Returns true if the current node is referenced.

Referenced elements are elements that do not render by itself, rather defines rendering properties for other.

List: altGlyphDef, clipPath, cursor, filter, linearGradient, marker, mask, pattern, radialGradient and symbol.

Examples

use svgdom::{Document, ElementType};

let doc = Document::from_str(
    "<svg xmlns='http://www.w3.org/2000/svg'><linearGradient/></svg>").unwrap();
let mut iter = doc.root().descendants();
assert_eq!(iter.next().unwrap().is_referenced(), false); // root
assert_eq!(iter.next().unwrap().is_referenced(), false); // svg
assert_eq!(iter.next().unwrap().is_referenced(), true); // linearGradient
