Enum rustler::error::Error [−][src]
pub enum Error { BadArg, Atom(&'static str), RaiseAtom(&'static str), RaiseTerm(Box<dyn Encoder>), Term(Box<dyn Encoder>), }
Expand description
Represents usual errors that can happen in a nif. This enables you to return an error from anywhere, even places where you don’t have an Env available.
Variants
Returned when the NIF has been called with the wrong number or type of arguments.
Atom(&'static str)
Encodes the string into an atom and returns it from the NIF.
RaiseAtom(&'static str)
Encodes an arbitrary Boxed Encoder and returns {:error, term}
from
the NIF. Very useful for returning descriptive, context-full errors.
