Cloudflare R2 is an object storage service that provides three interfaces: +//! +//! 1. **S3-compatible API** – Works with the existing [`AmazonS3`](crate::aws::AmazonS3) backend +//! 2. **Cloudflare REST API** – This module (uses `https://api.cloudflare.com/client/v4/`) +//! 3. **Workers Bindings** – For use within Cloudflare Workers runtime +//! +//! This module implements interface #2 (the native Cloudflare REST API), which uses +//! Bearer token authentication with a Cloudflare API token. +//! +//! ## Example +//! +//! ```no_run +//! # use object_store::cloudflare::CloudflareR2Builder; +//! # use object_store::ObjectStore; +//! # async fn example() -> Result<(), Box> { +//! let r2 = CloudflareR2Builder::new() +//! .with_account_id("my-account-id") +//! .with_bucket_name("my-bucket") +//! .with_api_token("my-api-token") +//! .build()?; +//! +//! // Use like any other ObjectStore +//! let path = object_store::path::Path::from("hello.txt"); +//! r2.put_opts(&path, "hello world".into(), Default::default()).await?; +//! let result = r2.get_opts(&path, Default::default()).await?; +//! let bytes = result.bytes().await?; +//! assert_eq!(&bytes[..], b"hello world"); +//! # Ok(()) +//! # } +//! ``` +//! +//! ## Multipart uploads +//! +//! Multipart uploads can be initiated with the [`ObjectStore::put_multipart_opts`] method. +//! R2 supports up to 10,000 parts per multipart upload, with each part being at most 5 GB. +//! The minimum part size is 5 MB (except for the last part). +//! +//! ## Configuration via environment variables +//! +//!

This module provides a direct binding to R2 from within a Cloudflare Worker, +//! bypassing the HTTP layer entirely. It wraps the [`worker::Bucket`] type +//! (which is a JavaScript FFI binding to the R2 bucket) and implements the +//! [`ObjectStore`] trait. +//! +//! This module is only available when: +//! - The `cloudflare-workers` feature is enabled +//! - The target is `wasm32-unknown-unknown` +//! +//! ## Usage +//! +//! ```ignore +//! use object_store::cloudflare::workers::CloudflareR2Workers; +//! use object_store::ObjectStore; +//! use worker::Env; +//! +//! // Inside a Worker request handler +//! async fn handle(env: Env) -> Result<(), Box> { +//! let bucket = env.bucket("MY_BUCKET").unwrap(); +//! let store = CloudflareR2Workers::new(bucket); +//! +//! let path = object_store::path::Path::from("hello.txt"); +//! store.put_opts(&path, "hello world".into(), Default::default()).await?; +//! let result = store.get_opts(&path, Default::default()).await?; +//! let bytes = result.bytes().await?; +//! assert_eq!(&bytes[..], b"hello world"); +//! Ok(()) +//! } +//! ``` +//! +//! ## Limitations +//! +//! - **Multipart uploads**: Supported (R2 Workers bindings support multipart) +//! - **Conditional operations**: `PutMode::Create` and `PutMode::Update` are supported +//! via `onlyIf` conditions +//! - **Copy**: Supported via the R2 `copy` binding +//! - **List**: Supported with prefix, delimiter, and cursor-based pagination +//! - **Attributes**: Content-type, cache-control, content-disposition, +//! content-encoding, content-language, and custom metadata are supported + +use crate::path::Path;
