Implementations

impl<T: PrimitiveTypeTag<T> + Default> Primitive<T>

pub fn new() -> Primitive<T>

Create a new type primitive

pub fn get(&self, type_inst: &mut TypeInstanceObject) -> Option<T>

Get a primitive value from the primitive descriptor.

This function will be valid only when it’s called from execution function and there’s type instance object has been created. Otherwise it will returns a failure

• type_inst: Type instance object where we read the primitive from

Return the read result, None indicates we are unable to read the data

pub fn set(&self, type_inst: &mut TypeInstanceObject, val: T) -> bool

Write a primitive to the primitive descriptor within current task context

This function will be valid only when it’s called from the execution function, because it requires the task context.

• type_inst: The type instance object where we want to write to

Return the operation result, if the operation has successuflly done.
