Value

Enum Value

pub enum Value {
    Void,
    Entity(EntityRef),
    Function(Arc<dyn ErasedFunction>),
    Float(f32),
    Vector(Vec3),
    String(Arc<CStr>),
}

Expand description

The type of individual values passed in and out of the QuakeC runtime. Note that, in most cases, Void will be converted to the default value for the type.

Variants§

Void

Corresponds to QuakeC’s void. Should rarely be used, and is mostly for the return value of functions that do not return any sensible value.

Entity(EntityRef)

An entity reference. See documentation for EntityRef for more details.

Function(Arc<dyn ErasedFunction>)

A function pointer. This requires some context to call, see userdata::Function.

Float(f32)

A single scalar float.

Vector(Vec3)

An {x, y, z} vector value.

String(Arc<CStr>)

A refcounted string pointer. Quake strings are not strictly ascii, but cannot have internal NUL, so CStr is used.

Implementations§

impl Value

pub const fn type_(&self) -> Type

The Type of this value.

pub fn field(&self, field: VectorField) -> Result<Value, TryScalarError>

Get a field of a value.

pub fn set( &mut self, field: VectorField, value: Value, ) -> Result<(), SetValueError>

Clone the source value to this value, with an optional field reference. Useful to implement userdata::EntityHandle::set, as sometimes QuakeC only wants to set a single field of a vector.
