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 of Callback

return_type: Option<Box<Type>>args: Vec<Type>

Function

Fields of Function

return_type: Box<Type>args: Vec<Type>

Float32

Int32

String

Color

Duration

PhysicalLength

LogicalLength

Angle

Percent

Image

Bool

Model

PathElements

Easing

Brush

Array(Box<Type>)

This is usually a model

Struct

Fields of Struct

fields: BTreeMap<String, Type>name: Option<String>node: Option<ObjectType>

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

impl Type

    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

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

impl From<Type> for PropertyDeclaration

fn from(ty: Type) -> Self
