Enum Value 

#[non_exhaustive]
pub enum Value {
    Void = 0,
    Number(f64),
    String(SharedString),
    Bool(bool),
    Image(Image),
    Model(ModelRc<Value>),
    Struct(Struct),
    Brush(Brush),
    Keys(Keys),
    DataTransfer(DataTransfer),
}

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)

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 does 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

Keys(Keys)

Correspond to the keys type in .slint

DataTransfer(DataTransfer)

Correspond to the data-transfer type in .slint

impl InterpolatedPropertyValue for Value

Animated bindings on sub-component properties need Value to support interpolation. Numeric and brush variants interpolate; everything else snaps. Numbers interpolate in f32 because animated numeric properties are f32-based — an f64 blend would leak rounding noise like 99.50000001117587 instead of 99.5.

Returns the interpolated value between self and target_value according to the progress parameter t that’s usually between 0 and 1. With certain animation easing curves it may over- or undershoot though.
