Enums

PaxAny

This type serves a similar purpose as Box<dyn Any>, but allows for special handling of some types, enabling things like coercion.

Variants

Builtin(PaxValue)

Built-in PAXEL/runtime value.

Any(Box<dyn Any>)

Arbitrary Rust value boxed for runtime storage.

PaxValue

Runtime container for polymorphic values, for evaluating PAXEL.

Two important traits are related to this type: ToFromPaxValue - responsible for converting to and from specific types (u8, String, Color, etc) CoercionRules - responsible for coercing a PaxValue to a specific type (possibly from multiple different variants)

Variants

Bool(bool)

Boolean value.

Numeric(Numeric)

Polymorphic numeric value.

String(String)

UTF-8 string value.

Size(Size)

Pax size value, such as 25px or 50%.

Percent(Percent)

Raw percent value.

Color(Box<Color>)

Pax color value.

Rotation(Rotation)

Pax rotation value.

Duration(Duration)

Pax animation duration value, such as 250ms, 1s, or 10f.

PathElement(Box<PathElement>)

Vector path element value.

Option(Box<Option<PaxValue>>)

Optional value.

Vec(Vec<PaxValue>)

Homogeneous or heterogeneous vector value.

Range(Box<PaxValue>, Box<PaxValue>)

Range value.

Object(Vec<(String, PaxValue)>)

Object value represented by named fields.

Enum(Box<(String, String, Vec<PaxValue>)>)

Enum value represented by type name, variant name, and payload values.

Traits

ImplToFromPaxAny

Marker trait for types that can be stored inside PaxAny without a built-in PaxValue representation.

If the type is part of PaxValue, implement CoercionRules instead.

ToFromPaxAny

Trait that marks a type as being representable as a PaxAny, and provides the implementation for going to/from that type. For all builtins this means going to/from a pax value. For others to a Box<dyn Any>. This is automatically Implemented for PaxValue types through the macro impl_to_from_pax_value!, and for other types by implementing the marker trait ImplToFromPaxAny.

ToPaxValue

Converts a Rust value into its built-in PaxValue representation.

This is exact conversion, not coercion; coercion is handled separately by CoercionRules.

Type Aliases

RcPaxValue

Shared runtime PaxValue handle.
