Rust-API: Builder: Should build be &mut self so that this can be turned into a trait object?

[MarkSchmitt]

Check the com-api/src/lib.rs (TODO: insert link to file in this repo once merged):

pub trait Builder {
...

  fn bild (self) -> Result<Self::Output>;

Should this be &mut self so that this can be turned into a trait object?
