Trait embedded_error_chain::ErrorCategory

pub trait ErrorCategory: Copy + Into<ErrorCode> + From<ErrorCode> + Debug {
    type L0: ErrorCategory;
    type L1: ErrorCategory;
    type L2: ErrorCategory;
    type L3: ErrorCategory;
    type L4: ErrorCategory;
    type L5: ErrorCategory;

    const NAME: &'static str;
    fn chainable_category_formatters() -> &'static [ErrorCodeFormatter] { ... }
}

A trait that implements the logic for debug printing and ErrorCode conversion. It also specifies the links to other error categories that allows Errors of different types to be chained.

Note: Only up to 6 linked error categories are allowed.
