Element Builder API

reView doesn't have a macro to support a syntax similar to jsx but instead provides an API to create the UI.

The main concept is that every Tag and every String could become a VNode.

For this reason both Tag, String and VElement implement the From<VNode> trait to obtain a VNode using into().

To attach attributes or children to a Tag element we could use a builder API.

Every Tag or VElement implements the ElementBuilder trait so we can call:

• with_child to attach a single child (the child should implement the From<VNode> trait)
• with_children to attach a vector of child (every element should implement). reView provide a children! macro to simplify the creation of the child vector
• with_attribute to attach an attribute specifing akey and a value
• with_attributes to attach a vector of attributes. A vector of attribute is a vector of tuple (key, value)
• with_event to attach an event specifing a EventType and an Event. reView provide a callback! macro to create an Event from a rust closure.

Using this API we can create a customized VElement that could be converted into a VNode with into().

Main.with_children(children!(
    Img.with_attribute("class", "logo")
        .with_attributes(vec!(
            ("src", "/assets/logo.png"), 
            ("alt", "reView logo")
        ))
        .with_event(OnClick, callback!(|| { log::info!("hello!!") }))
    H1.with_child("Hello World!"),
    Span.with_attribute("class", "subtitle")
        .with_children(children!(
            "from reView with ",
            I.with_attribute("class", "heart")
        ))
))
.into()
