RSX
This macro is the recommended way to describe a ui, it is a div that holds multiple elements
#[component]
fn App() -> Element {
rsx! {
button { "click me" }
text { "This is some text" }
}
}
rsx!
is really just a div, so you can just do something likersx! {
id: "root", class: "root",
button { "click me" }
text { "This is some text" }
}
Child values
If you want to add more children to values then just simply express it like a rsx!
let x = 69;
rsx! {
div {
text { "the number is {x}, Nice!" }
}
}
Formatted text
let x = 69;
rsx! {
text { "the number is {x}, Nice!" }
}
You can also do expressions after the string
text { "the number is {}, Nice!", x }
For loops
rsx! {
for (i in 0..5) { // () are required
text { "{i}" }
}
}
Attribute
You can change the element's struct fields by just providing some attributes before the children
rsx! {
text { class: "my_text" }
}
Handler functions
Instead of closures which are tricky to work with on structs, We use Handler
, It's basically a closure wrapped with a Arc<Mutex<T>>
rsx! {
button {
on_click: fn(btn: &mut Button, event, document) {
// do something
}
}
}
Handler functions (with dependents)
If you have a State<T>
and want to use it, you have to put a @ before the code block like this
let count = State::new();
rsx! {
button {
on_click: fn(btn: &mut Button, event, document) @count {
let count = count.use_state(); // locks count so it can be used
},
"Current count: {count}"
}
}
you can add multiple decedents by separating them via,
like: @var1, var2, var3
Static text
If your text doesn't use variables that will change you can put static
right before the text to signal that it's static.
let count = 69; // count won't change since it's not mutable
rsx! {
text {
static "Current count: {count}"
}
}
Instructions
Add an instruction by putting a @
before it, like this:
rsx! {
@SetStyle(css! { // the SetStyle instruction
"title": {
color: Green,
}
})
text { class: "title", static "Hello world!" }
}
Ghost elements
With a div
you can use tab (or shift+tab) to go through components, But sometimes an element doesn't really do anything, So to skip over the element you can use the ghost syntax %
. This makes it so that the element is not selectable.
rsx! {
%text { "This is a ghost title!!!!" }
button { "Click me!" }
}
