* feat(worker): add send_email binding support Adds a `SendEmail` binding and `EmailMessage` type so workers can dispatch email via the Cloudflare Email Sending service configured under `[[send_email]]` in wrangler.toml. Includes worker-sys bindings for `cloudflare:email`, a runnable example under `examples/send-email`, and integration tests. * feat(worker): add structured Email builder for send_email binding Extend the SendEmail binding to cover the public-beta builder overload in addition to the raw MIME path. Adds `Email`/`EmailBuilder`, `EmailAddress`, `EmailAttachment` (with `AttachmentContent::{Base64, Binary}`), and `EmailSendResult { message_id }`. `SendEmail::send` now takes `&Email`; the raw MIME path moves to `SendEmail::send_mime(&EmailMessage)`. * address pr comments * remove miniflare workaround cloudflare/workers-sdk#13577 landed * cleanup comments & example readme * use ts-gen for email * Auto-gen email bindings via ts-gen anonymous interface synthesis Drops the hand-written Email/EmailBuilder/EmailAddress/EmailAttachment types in worker/src/send_email.rs in favour of the auto-generated SendEmailBuilder, EmailAddress, EmailAttachment, etc. that ts-gen now synthesises from the d.ts. send_email.rs is reduced to the EnvBinding trait impl on the auto-gen SendEmail extern type and re-exports. types/email.d.ts renames the global EmailMessage interface to StructuredEmailMessage to keep it unambiguously distinct from the cloudflare:email-imported EmailMessage constructor class. The chompfile prepends a `use email::EmailMessage` to the generated file so the top-level send(message) signature resolves cross-module — removable once ts-gen handles same-file module imports natively. All 133 npm tests pass; both legacy raw-MIME and modern structured send paths work end-to-end. * add new_with_readable_stream test * Pull cross-module qualification + new builder ergonomics from ts-gen ts-gen learned three things since the last sync that simplify the email surface here: * Cross-module type references emit qualified Rust paths (`&email::EmailMessage` from a `Global` extern block referencing the `cloudflare:email` class). Drops the `chompfile.toml` postprocess that was prepending `use email::EmailMessage;` to the generated file. * Built-in `web_sys` defaults — `Headers`, `Event`, `ReadableStream`, etc. resolve to `::web_sys::*` automatically, so those `--external` flags are redundant. Only the project-specific `Env` and `ExecutionContext` mappings remain in the chompfile. * New dictionary builder shape: required fields go through the constructor, `build()` is infallible, literal discriminators collapse into the function name. Call sites update from `SendEmailBuilder::builder().from(x).build()?` to `SendEmailBuilder::builder(from, to, subject).build()` (or `::new(from, to, subject)` when no optionals are needed). `types/email.d.ts` collapses to a single `class EmailMessage` inside `declare module "cloudflare:email"`. The previous global-interface + module-class split (mirroring upstream `@cloudflare/workers-types`) was producing two distinct Rust types that both lowered to the same JS object, which forced an `unchecked_ref` at the `reply()` call site. Collapsed to one type they're indistinguishable in Rust. `worker/src/send_email.rs` keeps the [`EnvBinding`] impl on top of the auto-gen `SendEmail` extern type, plus a `#[cfg(test)]` compile check that `SendEmail: Send` (which it is already, via the upstream `JsValue: Send + Sync` change — no `unsafe impl Send` needed). * Use FixedLengthStream Deref instead of unchecked_into in mime-stream test `FixedLengthStream` already has `extends = web_sys::TransformStream` in `worker-sys`, so wasm-bindgen auto-generates `Deref<Target = TransformStream>` and `fixed.readable()` resolves through it. The previous `fixed.unchecked_into::<web_sys::TransformStream>().readable()` was unnecessarily defensive — drop the cast plus the now-unused `JsCast` and `web_sys` imports. * Fmt + advance ts-gen submodule to PR branch HEAD CI's rustfmt --check flagged the dispatch_structured signature. Apply fmt and bump the ts-gen submodule pointer to the latest PR #8 commit (CONVENTIONS.md rationale + emit cleanup). * Pull doc-comment generation from ts-gen PR #9 Each `new*` and `builder*` variant now ships with a doc block listing its inlined literal discriminants under `# Inlined fields` and the caller-supplied parameters under `# Parameters`, sourced from the original getter JSDoc. * Advance ts-gen submodule to merged main ts-gen PR #9 (doc comments on dictionary builder variants) merged. Bump the submodule pointer to the merge commit on main; the generated `worker/src/email.rs` is unchanged from the PR-branch output. * Advance ts-gen submodule to merged main ts-gen PR #10 (h2 headings + dash-separated bullets in builder docs) merged. Bump the submodule pointer and regenerate `worker/src/email.rs` with the updated doc format. --------- Co-authored-by: Guy Bedford <gbedford@cloudflare.com>
