Struct svgdom::Attributes

pub struct Attributes(_);

An attributes list.

Methods

impl Attributes

fn new() -> Attributes

Constructs a new attribute.

Warning: this method is for private use only. Never invoke it directly.

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.

Panics

During insert of a linked attribute. Use Node::set_attribute() instead.

Will panic only in debug build.

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

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

Node attribute value can be set only via Node::set_attribute() method.

fn insert_impl(&mut self, attr: Attribute)

Inserts a new link attribute.

Warning: this method is for private use only. Never invoke it directly.

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

Removes an existing attribute.

Panics

During remove of a linked attribute. Use Node::remove_attribute() instead.

Will panic only in debug build.

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

Removes an existing attribute.

Warning: this method is for private use only. Never invoke it directly.

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<SvgAttrFilter, 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<SvgAttrFilterMut, 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.

Panics

During remove of a linked attribute. Use Node::remove_attribute() instead.

Will panic only in debug build.

Trait Implementations
