pub enum Attr<'a> {
Plain {
name: Symbol,
value: &'a Expr<'a>,
},
Bind {
field: Symbol,
},
Class {
name: Symbol,
cond: &'a Expr<'a>,

Directive {

}Expand description
One attribute-position item of an element, in source order.
Variants§
Plain
name=<expr> — a plain (possibly dynamic) attribute.
Bind
bound to <field> / bind={field} — two-way form binding.
Class
class:name={condition} — the class is present exactly while the condition holds.
Directive
A declared ## Directive used as an attribute (tooltip={text}).

fn into_any(self: Box<T>) -> Box<dyn Any>
Convert
Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can
then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.§fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>
fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>
Convert
Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be
further downcast into Rc<ConcreteType> where ConcreteType implements Trait.§fn as_any(&self) -> &(dyn Any + 'static)
fn as_any(&self) -> &(dyn Any + 'static)
Convert
&Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &Any’s vtable from &Trait’s.§fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
Convert
&mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &mut Any’s vtable from &mut Trait’s.
