AWS SDK for Zig
|
|
===============
|
|
|
|
[Zig 0.13](https://ziglang.org/download/#release-0.13.0):
|
|
|
|
[](https://git.lerch.org/lobo/aws-sdk-for-zig/actions?workflow=build.yaml&state=closed)
|
|
|
|
[Last Mach Nominated Zig Version](https://machengine.org/about/nominated-zig/):
|
|
|
|
[](https://git.lerch.org/lobo/aws-sdk-for-zig/actions?workflow=zig-mach.yaml&state=closed)
|
|
|
|
[Nightly Zig](https://ziglang.org/download/):
|
|
|
|
[](https://git.lerch.org/lobo/aws-sdk-for-zig/actions?workflow=zig-nightly.yaml&state=closed)
|
|
|
|
Current executable size for the demo is 980k after compiling with -Doptimize=ReleaseSmall
|
|
in x86_linux, and will vary based on services used. Tested targets:
|
|
|
|
* x86_64-linux
|
|
* riscv64-linux\*
|
|
* aarch64-linux
|
|
* x86_64-windows
|
|
* arm-linux
|
|
* aarch64-macos
|
|
* x86_64-macos
|
|
|
|
Tested targets are built, but not continuously tested, by CI.
|
|
|
|
\* On Zig 0.12/0.13, riscv64-linux disabled due to [LLLM's O(N^2) codegen](https://github.com/ziglang/zig/issues/18872)
|

Zig-Develop Branch
|
|
------------------
|
|
|
|
This branch is intended for use with the in-development version of Zig. This
|
|
starts with 0.12.0-dev.3180+83e578a18. This is aligned with [Mach Engine's Nominated
|
|
Zig Versions](https://machengine.org/about/nominated-zig/). Nightly zig versions
|
|
are difficult to keep up with and there is no special effort made there, build
|
|
status is FYI (and used as a canary for nominated zig versions).
|
|
|
|
Building
|
|
--------
|
|
|
|
`zig build` should work. It will build the code generation project, fetch model
|
|
files from upstream AWS Go SDK v2, run the code generation, then build the main
|
|
project with the generated code. Testing can be done with `zig test`.
|
|
|
|
|
|
Using
|
|
-----
|
|
|
|
This is designed for use with the Zig package manager, and exposes a module
|
|
called "aws". Set up `build.zig.zon` and add the dependency/module to your project
|
|
as normal and the package manager should do its thing. A full example can be found
|
|
in [/example](example/README.md).
|
|
|
|
Configuring the module and/or Running the demo
|
|
----------------------------------------------
|
|
|
|
This library mimics the aws c libraries for it's work, so it operates like most
|
|
other 'AWS things'. [/src/main.zig](src/main.zig) gives you a handful of examples
|
|
for working with services. For local testing or alternative endpoints, there's
|
|
no real standard, so there is code to look for `AWS_ENDPOINT_URL` environment
|
|
variable that will supersede all other configuration.
|
|
|
|
Limitations
|
|
-----------
|
|
|
|
WebIdentityToken is not yet implemented.
|
|
|
|
TODO List:
|
|
|
|
* Json parsing is based on a fork of the 0.9.0 (maybe earlier?) json parser.
|
|
This needs a re-visit. Note also that a json.zig file is embedded/copied
|
|
from the codegen project, so that also needs a second look.
|
|
* Take a look to see about compilation speed. With codegen caching this is
|
|
reasonable, but still takes longer than needed.
|
|
* Upgrade the model files. This is a simple tasks, but I'd like the first
|
|
item on this list to be completed first.
|
|
* Implement sigv4a signing
|
|
* Implement jitter/exponential backoff
|
|
* Implement timeouts and other TODO's in the code
|
|
* Add option to cache signature keys
|
|
|
|
Services without TLS 1.3 support
|
|
--------------------------------
|
|
|
|
All AWS services should support TLS 1.3 at this point, but there are many regions
|
|
and several partitions, and not all of them have been tested, so your mileage
|
|
may vary. If something doesn't work, please submit an issue to let others know.
|
|
|
|
Dependency tree
|
|
---------------
|
|
|
|
