Implementations§

Source §

impl<'a> Element<'a>

Source

pub fn new( (ele_type, attributes): (&'a str, HashMap<String, &'a str>), ) -> Rc<Self>

new a element without children

§Example

use std::collections::HashMap;
use svg_simple_parser::Element;

Element::new(("rect",HashMap::from([("width".to_owned(), "100"),("height".to_owned(), "100")])));

Source

pub fn new_width_children( (ele_type, attributes, children): (&'a str, HashMap<String, &'a str>, Vec<Rc<Element<'a>>>), ) -> Rc<Self>

new a element with children

§Example

use std::collections::HashMap;
use svg_simple_parser::Element;

let child = Element::new(("rect",HashMap::from([("width".to_owned(), "100"),("height".to_owned(), "100")])));
Element::new_width_children(("rect",HashMap::from([("width".to_owned(), "100"),("height".to_owned(), "100")]),vec![child]));

Source

pub fn add_child(self: &Rc<Element<'a>>, new_item: Rc<Element<'a>>)

add a element to the children of the element.

§Example

use std::collections::HashMap;
use svg_simple_parser::Element;

let parent = Element::new(("rect",HashMap::from([("width".to_owned(), "100"),("height".to_owned(), "100")])));
let child = Element::new(("rect",HashMap::from([("width".to_owned(), "100"),("height".to_owned(), "100")])));
Element::add_child(parent.clone(),child.clone());
assert_eq!(parent.borrow().children.borrow().get(0),Some(&child));

Source

pub fn add_children(self: &Rc<Element<'a>>, new_items: Vec<Rc<Element<'a>>>)

add a list of element to the children of the element.

§Example

use std::collections::HashMap;
use svg_simple_parser::Element;

let parent = Element::new(("rect",HashMap::from([("width".to_owned(), "100"),("height".to_owned(), "100")])));
let child = Element::new(("rect",HashMap::from([("width".to_owned(), "100"),("height".to_owned(), "100")])));
Element::add_children(parent.clone(),vec![child.clone()].as_mut());
assert_eq!(parent.borrow().children.borrow().get(0),Some(&child));
