Lib.rs

features enable surrealism_ui, Cargo.toml file like example:

[dependencies]
slint = "1.8.0"

[build-dependencies]
jui = { version = "0.2.1", features = ["surrealism_ui"] }

use SurrealismUI in you slint file:

// support all component
// import { SButton } from "@surrealism_all";

// support single component
import { SButton } from "@surrealism/button/index.slint";

export component App inherits Window {
    SButton {}
}

more SurrealismUI see: SurrealismUI wiki or SurrealismUI Book

if you want use alias import SurrealismUI, example for this build.rs:

use jui::surrealism_ui::SurrealismUI;

pub fn main() {
    let separator = jui::cbsk_file::separator;
    // alias import is sui, example import: 
    // import { SButton } from "@sui/button/index.slint";
    let surrealism_ui = SurrealismUI::new_with_alias("sui");
    jui::compile_with_surrealism_ui(format!("view{separator}main.slint"), surrealism_ui).unwrap();
}
