Trait GuestErrorType

pub trait GuestErrorType {
    // Required method
    fn success() -> Self;
}

A trait for types which are used to report errors. Each type used in the first result position of an interface function is used, by convention, to indicate whether the function was successful and subsequent results are valid, or whether an error occurred. This trait allows wiggle to return the correct value when the interface function’s idiomatic Rust method returns Ok(<rest of return values>).

Required Methods

fn success() -> Self

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
