Struct svgdom::Attributes

pub struct Attributes(_);

Wrapper around attributes list.

More low level API than in Node, but it supports getting a reference to the attribute, and not only copy like Node's API.

Use with care, since it didn't perform many check from Node's API.

Methods

impl Attributes

fn new() -> Attributes

Constructs a new attribute.

Warning: newer construct it manually. All nodes have Attributes by default.

fn get<'a, N>(&self, name: N) -> Option<&Attribute> where AttributeNameRef<'a>: From<N>

Returns an optional reference to Attribute.

fn get_mut<'a, N>(&mut self, name: N) -> Option<&mut Attribute> where AttributeNameRef<'a>: From<N>

Returns an optional mutable reference to Attribute.

fn get_value<'a, N>(&self, name: N) -> Option<&AttributeValue> where AttributeNameRef<'a>: From<N>

Returns an optional reference to AttributeValue.

fn get_value_mut<'a, N>(&mut self, name: N) -> Option<&mut AttributeValue> where AttributeNameRef<'a>: From<N>

Returns an optional mutable reference to AttributeValue.

fn insert(&mut self, attr: Attribute)

Inserts a new attribute. Previous will be overwritten.

Warning: this method did not perform any checks for linked attributes. If you want to insert an linked attribute - use Node::set_link_attribute().

fn insert_from<'a, N, T>(&mut self, name: N, value: T) where AttributeNameRef<'a>: From<N>, N: Copy, AttributeValue: From<T>

Creates a new attribute from name and value and inserts it. Previous will be overwritten.

Warning: this method did not perform any checks for linked attributes. If you want to insert an linked attribute - use Node::set_link_attribute().

fn remove<'a, N>(&mut self, name: N) where AttributeNameRef<'a>: From<N>

Removes an existing attribute.

Warning: this method did not perform any checks for linked attributes. If you want to remove an linked attribute - use Node::remove_attribute().

fn contains<'a, N>(&self, name: N) -> bool where AttributeNameRef<'a>: From<N>

Returns true if the container contains an attribute with such id.

fn len(&self) -> usize

Returns count of the attributes.

fn is_empty(&self) -> bool

Returns true if attributes is empty.

fn iter(&self) -> Iter<Attribute>

Returns an iterator.

fn iter_mut(&mut self) -> IterMut<Attribute>

Returns a mutable iterator.

fn iter_svg<'a>(&'a self)
                -> Map<Filter<Iter<'a, Attribute>, fn(_: &&Attribute) -> bool>, fn(_: &'a Attribute) -> (AttributeId, &'a Attribute)>

Returns an iterator over SVG attributes.

Shorthand for: iter().filter(|a| a.is_svg()).map(|a| (a.id().unwrap(), a))

fn iter_svg_mut<'a>(&'a mut self)
                    -> Map<Filter<IterMut<'a, Attribute>, fn(_: &&mut Attribute) -> bool>, fn(_: &'a mut Attribute) -> (AttributeId, &'a mut Attribute)>

Returns a mutable iterator over SVG attributes.

Shorthand for: iter_mut().filter(|a| a.is_svg()).map(|a| (a.id().unwrap(), a))

fn retain<F>(&mut self, f: F) where F: FnMut(&Attribute) -> bool

Retains only elements specified by the predicate.
