Struct StatePropertyWriter 

pub struct StatePropertyWriter<'a> { /* private fields */ }

Writing handle for properties.

Implementations

impl<'a> StatePropertyWriter<'a>

pub fn new(head: SpaceHead<'a>) -> Self

Create a new property writer that uses the given space head.

pub fn init<'b, A: Atom<'a, 'b>>( &'b mut self, urid: URID<A>, parameter: A::WriteParameter, ) -> Result<A::WriteHandle, StateErr>

Initialize the property.

This works like any other atom writer: You have to provide the URID of the atom type you want to write, as well as the type-specific parameter. If the property hasn’t been initialized before, it will be initialized and the writing handle is returned. Otherwise, Err(StateErr::Unknown) is returned.
