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

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
