impl<'b> TraitBuilder<'b>

pub fn new( env: &'b mut Environment, parent_chunk: Option<&'b Chunk>, name: Rc<str>, ) -> Result<Self, ErrorKind>

pub fn add_method( &mut self, name: Rc<str>, arity: u16, ) -> Result<u16, ErrorKind>

Adds a function into the trait and returns its method ID and function ID.

The arity does not include the self parameter.

pub fn build(self) -> (Opr24, &'b mut Environment)

Finishes building the trait, returns its trait ID, and gives back the mutable reference to the environment.
