From 8196dcfb099135a1464dd4c559edcc61570c4b88 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Tue, 3 Mar 2026 03:15:59 +0000 Subject: [PATCH 1/4] feat: typed interfaces, explicit id/list/payload params, proper error returns - Refactored `Creator`, `Reader`, `Updater`, `Deleter`, and `DataValidator` interfaces to replace variadic `data ...any` with explicitly typed parameters (`payload any`, `id string`) and strict error returns. - Added `List() (any, error)` to `Reader` interface to resolve ambiguity in generic reads. - Updated `CallHandler` logic to correctly iterate, filter out system injected objects (`*http.Request`, `context.Context`), and extract the precise payload before delegation. - Removed `github.com/tinywasm/binary` as the default codec in `crudp.go` and from the dependencies, enforcing explicit codec configuration. - Migrated tests (`shared_test.go`, `integration_stlib_test.go`) to utilize `github.com/tinywasm/json`. - Updated docs, example applications, and integration test mocks to reflect the new API and "Handler Wrapper" design pattern.
