Enum rustler::error::Error

source ·
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§

§

BadArg

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)

§

RaiseTerm(Box<dyn Encoder>)

§

Term(Box<dyn Encoder>)

Encodes an arbitrary Boxed Encoder and returns {:error, term} from the NIF. Very useful for returning descriptive, context-full errors.
