Enum HandlerError 

pub enum HandlerError {
    Host(String),
    ArgsMismatch(&'static str),
    Other(String),
}

A handler call failed for a reason other than a graceful contract error.

Variants

Host(String)

The host returned an error that is not a contract error.

ArgsMismatch(&'static str)

The runner passed arguments of the wrong type; indicates a framework bug.

Other(String)

Any other failure the handler wants to surface as a bug.
