Slint interpreter library

With this crate, you can load a .slint file at runtime and show its UI.

You only need to use this crate if you do not want to use pre-compiled .slint code, which is the normal way to use Slint, using the slint crate

The entry point for this crate is the [ComponentCompiler] type, which you can use to create [ComponentDefinition] with the [ComponentCompiler::build_from_source] or [ComponentCompiler::build_from_path] functions.

Note about async functions

Compiling a component is async but in practice, this is only asynchronous if [ComponentCompiler::set_file_loader] is set and its future is actually asynchronous. If that is not used, then it is fine to use a very simple executor, such as the one provided by the spin_on crate

Examples

This example loads a .slint dynamically from a path and show errors if any:

use slint_interpreter::{ComponentDefinition, ComponentCompiler, ComponentHandle};

let mut compiler = ComponentCompiler::default();
let definition =
spin_on::spin_on(compiler.build_from_path("hello.slint"));
# #[cfg(feature="print_diagnostics")]
slint_interpreter::print_diagnostics(&compiler.diagnostics());
if let Some(definition) = definition {
let instance = definition.create();
instance.run();
}

This example load a .slint from a string and set some properties:

use slint_interpreter::{ComponentDefinition, ComponentCompiler, Value, SharedString, ComponentHandle};

let code = r#"
export MyWin := Window {
property <string> my_name;
Text {
text: "Hello, " + my_name;
}
}
"#;

let mut compiler = ComponentCompiler::default();
let definition =
spin_on::spin_on(compiler.build_from_source(code.into(), Default::default()));
assert!(compiler.diagnostics().is_empty());
let instance = definition.unwrap().create();
instance.set_property("my_name", Value::from(SharedString::from("World"))).unwrap();
# return; // we don't want to call run in the tests
instance.run();
