Enum slint_interpreter::Value
source · #[non_exhaustive]#[repr(u8)]pub enum Value {
Void = 0,

}Expand description
This is a dynamically typed value used in the Slint interpreter.
It can hold a value of different types, and you should use the
From or TryFrom traits to access the value.
use core::convert::TryInto;
// create a value containing an integer
let v = Value::from(100u32);
assert_eq!(v.try_into(), Ok(100u32));Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
Void = 0
There is nothing in this value. That’s the default. For example, a function that do not return a result would return a Value::Void
Number(f64)
An int or a float (this is also used for unit based type such as length or angle)
String(SharedString)
Correspond to the string type in .slint
Bool(bool)
Correspond to the bool type in .slint
Image(Image)
Correspond to the image type in .slint
Model(ModelRc<Value>)
A model (that includes array in .slint)
Struct(Struct)
An object
Brush(Brush)
Correspond to brush or color type in .slint. For color, this is then a Brush::SolidColor

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.§impl<T> Instrument for T
