Enum ErrorClass 

#[non_exhaustive]
pub enum ErrorClass {
    Syntax,
    DataModel,
    Resolution,
    MessageFunction,
}

The category of an ErrorKind (spec/errors.md).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Syntax

The source is not well-formed.

DataModel

The message is well-formed but not valid.

Resolution

A value cannot be determined at runtime.

MessageFunction

An error from, or specific to, a function handler.
