Variants

Invalid

Correspond to an uninitialized type, or an error

Void

The type of an expression that return nothing

InferredProperty

The type of a property two way binding whose type was not yet inferred

InferredCallback

The type of a callback alias whose type was not yet inferred

Component(Rc<Component>)

Builtin(Rc<BuiltinElement>)

Native(Rc<NativeClass>)

Callback

Fields

return_type: Option<Box<Type>>

args: Vec<Type>

Function

Fields

return_type: Box<Type>

args: Vec<Type>

Float32

Int32

String

Color

Duration

PhysicalLength

LogicalLength

Angle

Percent

Image

Bool

Model

PathData

Easing

Brush

Array(Box<Type>)

This is usually a model

Struct

Fields

fields: BTreeMap<String, Type>

name: Option<String>

When declared in .slint as struct Foo := { }, then the name is “Foo” When there is no node, but there is a name, then it is a builtin type

node: Option<ObjectType>

When declared in .slint, this is the node of the declaration.

Enumeration(Rc<Enumeration>)

UnitProduct(Vec<(Unit, i8)>)

A type made up of the product of several “unit” types. The first parameter is the unit, and the second parameter is the power. The vector should be sorted by 1) the power, 2) the unit.

ElementReference

LayoutCache

This is a SharedArray<f32>

Implementations

List of sub properties valid for the auto completion

pub fn lookup_type_for_child_element(
    &self,
    name: &str,
    tr: &TypeRegister
) -> Result<Type, String>

pub fn lookup_member_function(&self, name: &str) -> Expression

pub fn as_builtin(&self) -> &BuiltinElement

Assume this is a builtin type, panic if it isn’t

pub fn as_native(&self) -> &NativeClass

Trait Implementations

impl Clone for Type

fn clone(&self) -> Type

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Type

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Type

fn default() -> Self

Returns the “default value” for a type.

impl Display for Type

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl From<Type> for PropertyDeclaration

fn from(ty: Type) -> Self
