# Examples
All examples are runnable and meant to be read as usage docs.
They follow the same layers as the crate docs:
- choose `Auth`
- build a `Client` or `BlockingClient`
- call `objects()` or `buckets()`
- work with public `s3::types` outputs
## Local / S3-compatible endpoint
Most async examples support:
- `S3_TEST_ENDPOINT` (e.g. `http://127.0.0.1:9000`)
- `S3_TEST_REGION` (default: `us-east-1`)
- `S3_TEST_BUCKET` (required for object ops)
- `AWS_ACCESS_KEY_ID` / `AWS_SECRET_ACCESS_KEY`
- `S3_TLS_ROOT_STORE` (optional: `backend-default` / `webpki` / `system`)
- `S3_CREDENTIALS_TLS_ROOT_STORE` (optional, IMDS/STS examples only: `backend-default` / `webpki` / `system`)
## Index
### Core object and bucket flows
- `async_put_get_delete.rs`: basic put/get/head/delete
- `async_put_stream.rs`: streaming upload (requires `Content-Length`)
- `async_list_buckets.rs`: list buckets
- `async_list_objects.rs`: list objects v2 + pagination
- `async_delete_objects_batch.rs`: batch delete (Content-MD5 included)
- `async_copy_object.rs`: copy object + replace metadata
- `async_multipart_upload.rs`: multipart upload (`--features multipart`)
### Auth, presign, and endpoint presets
- `presign_get.rs`: presign with static credentials
- `async_presign_build_async.rs`: presign with a credentials provider (`build_async`)
- `async_auth_imds.rs`: IMDS credentials (`--features credentials-imds`)
- `async_auth_web_identity.rs`: web identity credentials (`--features credentials-sts`)
- `minio_local_put_get_delete.rs`: `providers::minio_local()` preset (`--features providers`)
- `r2_put_get_delete.rs`: Cloudflare R2 preset (`--features providers`); optional `R2_JURISDICTION` (for example `eu`, `fedramp`) for jurisdiction-restricted buckets
### TLS and blocking flows
- `async_tls_root_store.rs`: async request TLS root policy (`S3_TLS_ROOT_STORE`)
- `blocking_put_get_delete.rs`: blocking put/get/delete
- `blocking_list_buckets.rs`: blocking list buckets
- `blocking_presign_get.rs`: blocking presign with static credentials
- `blocking_tls_root_store.rs`: blocking request TLS root policy (`S3_TLS_ROOT_STORE`)
