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`

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
