Enum RustCallError

pub enum RustCallError {
    Error(RustBuffer),
    InternalError(String),
}

Error type for Rust scaffolding calls

This enum represents the fact that there are two ways for a scaffolding call to fail:

• Expected errors (the Rust function returned an Err value).
• Unexpected errors (there was a failure calling the Rust function, for example the failure to lift the arguments).

Variants

Error(RustBuffer)

The Rust function returned an Err value.

The associated value is the serialized Err value.

InternalError(String)

There was a failure to call the Rust function, for example a failure to lift the arguments.

The associated value is a message string for the error.
