Enum EvalError 

pub enum EvalError {
    Unsupported,
    Threw {
        name: String,
        message: String,
    },
    ViewGone,
    Engine(String),
}

Why an evaluation did not produce a value.

Variants

Unsupported

This backend has no engine to evaluate in (web-dom’s <iframe>, or no renderer at all).

Threw

The script threw. name/message come from the caught exception; a cyclic value that JSON.stringify refuses arrives here too, as a TypeError.

Fields

name: String

message: String

ViewGone

The web view was never realized, or went away before the reply arrived.

Engine(String)

The engine ran but the reply did not decode; the raw payload is included.
