  • trait TypeDiagnostics extends AnyRef

    An interface to enable higher configurability of diagnostic messages regarding type errors.

    An interface to enable higher configurability of diagnostic messages regarding type errors. This is barely a beginning as error messages are distributed far and wide across the codebase. The plan is to partition error messages into some broad groups and provide some mechanism for being more or less verbose on a selective basis. Possible groups include such examples as

    arity errors kind errors variance errors ambiguity errors volatility/stability errors implementation restrictions

    And more, and there is plenty of overlap, so it'll be a process.

    Deprecated

    (Since version 2.12.16) Use formatString.format(value) instead of value.formatted(formatString), or use the f"" string interpolator. In Java 15 and later, formatted resolves to the new method in String which has reversed parameters.
