Patch Changes

  • #2320 016108a Thanks @gcanti! - Add Schema.isGUID and update Schema.isUUID to accept the RFC 9562 max UUID.

  • #2319 95c03d2 Thanks @fubhy! - Add support for configuring Scalar API reference pages with a custom fetch implementation.

  • #2318 07299a3 Thanks @gcanti! - Replace the Schema.Error and Schema.Defect schema constants with constructor functions, Schema.Error() and Schema.Defect().

    Unify Schema.ErrorWithStack into Schema.Error({ includeStack: true }) and Schema.DefectWithStack into Schema.Defect({ includeStack: true }).

    Error causes are encoded by default using the same JSON defect encoding semantics used by Schema.Defect; pass { excludeCause: true } to omit nested cause data.

    Equivalent Schema.Error and Schema.Defect options are canonicalized, so repeated constructor calls with the same option values reuse the same schema.

    Schema.Defect() now models defects as unknown values with a JSON encoded form. Error-shaped JSON objects with a string message decode to JavaScript Error values, so non-Error objects such as { message: "boom" } do not round-trip unchanged. Other non-Error values are normalized through JSON serialization, with non-JSON values falling back to Effect’s formatted string representation.
