From 52eec76ce328dce9131569e408ec04bafdc98f3d Mon Sep 17 00:00:00 2001 From: Andy Date: Mon, 26 Jan 2026 03:06:03 +0800 Subject: [PATCH 1/3] feat: Add native Cloudflare D1 database driver support Add a native D1 driver for Sea-ORM that enables seamless integration with Cloudflare Workers D1 databases. This driver provides: - D1Connector and D1Connection types wrapping worker::D1 binding - Full SQL execution support (execute, query_one, query_all) - D1QueryExecutor trait for Entity queries (works around wasm-bindgen Send bound) - D1Row and D1ExecResult types for result handling - TryGetable support for D1-specific types Example usage: let db = sea_orm::Database::connect_d1(d1).await?; let cakes = cake::Entity::find().all(&db).await?; Breaking change: None Feature: D1 database driver for Cloudflare Workers Co-Authored-By: Claude --- Cargo.toml | 3 + examples/d1_example/Cargo.toml | 32 ++ examples/d1_example/README.md | 97 ++++ examples/d1_example/src/cake.rs | 21 + examples/d1_example/src/lib.rs | 317 +++++++++++++ src/database/db_connection.rs | 133 +++++- src/database/mod.rs | 27 ++ src/database/stream/query.rs | 6 + src/driver/d1.rs | 813 ++++++++++++++++++++++++++++++++ src/driver/mod.rs | 4 + src/executor/execute.rs | 7 + src/executor/query.rs | 236 ++++++++- 12 files changed, 1690 insertions(+), 6 deletions(-) create mode 100644 examples/d1_example/Cargo.toml create mode 100644 examples/d1_example/README.md create mode 100644 examples/d1_example/src/cake.rs create mode 100644 examples/d1_example/src/lib.rs create mode 100644 src/driver/d1.rs diff --git a/Cargo.toml b/Cargo.toml index 2e96c4ca9..7a545c216 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -28,6 +28,7 @@ features = [ "postgres-array", "postgres-vector", "sea-orm-internal", + "d1", ] rustdoc-args = ["--cfg", "docsrs"] @@ -85,6 +86,7 @@ tracing = { version = "0.1", default-features = false, features = [ ] } url = { version = "2.2", default-features = false } uuid = { version = "1", default-features = false, optional = true } +worker = { version = "0.7", default-features = false, optional = true } [dev-dependencies] dotenv = "0.15" @@ -148,6 +150,7 @@ runtime-tokio = ["sqlx?/runtime-tokio"] runtime-tokio-native-tls = ["sqlx?/runtime-tokio-native-tls", "runtime-tokio"] runtime-tokio-rustls = ["sqlx?/runtime-tokio-rustls", "runtime-tokio"] rusqlite = [] +d1 = ["worker/d1", "mock"] schema-sync = ["sea-schema"] sea-orm-internal = [] seaography = ["sea-orm-macros/seaography"] diff --git a/examples/d1_example/Cargo.toml b/examples/d1_example/Cargo.toml new file mode 100644 index 000000000..c22a799ca --- /dev/null +++ b/examples/d1_example/Cargo.toml @@ -0,0 +1,32 @@ +[package] +authors = ["Sea ORM Contributors"] +edition = "2024" +name = "sea-orm-d1-example" +publish = false +rust-version = "1.85.0" +version = "0.1.0" + +[workspace] + +[package.metadata.release] +release = false + +# https://github.com/rustwasm/wasm-pack/issues/1247 +[package.metadata.wasm-pack.profile.release] +wasm-opt = false + +[lib] +crate-type = ["cdylib"] +path = "src/lib.rs" + +[dependencies] +serde = { version = "1", features = ["derive"] } +serde_json = "1" + +worker = { version = "0.7", features = ["d1"] } + +sea-orm = { path = "../../", default-features = false, features = [ + "d1", + "with-json", + "macros", +]} diff --git a/examples/d1_example/README.md b/examples/d1_example/README.md new file mode 100644 index 000000000..214fc73ed --- /dev/null +++ b/examples/d1_example/README.md @@ -0,0 +1,97 @@ +# Sea-ORM D1 Example + +This example demonstrates how to use Sea-ORM with Cloudflare D1. + +## Prerequisites + +- [Rust](https://rustup.rs/) installed +- [wasm-pack](https://rustwasm.github.io/wasm-pack/installer/) installed +- [Wrangler](https://developers.cloudflare.com/workers/cli-wrangler/install-update/) CLI installed + +## Setup + +### 1.

Cloudflare D1 database driver for Sea-ORM +//! +//! This module provides native D1 support for Sea-ORM, allowing you to use +//!

Due to `wasm-bindgen` futures not being `Send`, the standard `ConnectionTrait` +//! and `TransactionTrait` cannot be implemented for D1.

Use [`D1Connection::transaction()`] +//! directly, but be aware D1 doesn't guarantee ACID transactions. +//! - **Streaming**: D1 does not support streaming queries. Use `query_all()` to load all results. +//! - **Join queries**: [`D1QueryExecutor`] only supports simple `Select` queries. +//! For joins, use raw SQL with [`D1Connection`]. +//! - **No `ConnectionTrait`**: The standard Sea-ORM connection interface isn't available. +//!
