AWS SDK for Zig (zig native branch)
This SDK currently supports all AWS services except services using the restXml protocol (4 services including S3). See TODO list below.
Current executable size for the demo is 1.6M (90k of which is the AWS PEM file, and approximately 600K for XML services) after compiling with -Drelease-safe and stripping the executable after compilation. This is for 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.
Building
zig build should work. It will build the code generation project, run
the code generation, then build the main project with the generated code.
First time build should use zig build -Dfetch to fetch dependent packages
(zfetch and friends).
Running
This library mimics the aws c libraries for it's work, so it operates like most
other 'AWS things'. 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. Note that an alternative endpoint may
require passing in a client option to specify an different TLS root certificate
(pass null to disable certificate verification).
The old branch exists for posterity, and supports x86_64 linux. The old branch is deprecated.
Limitations
There are many nuances of AWS V4 signature calculation. S3 is not supported because it uses many of these test cases. WebIdentityToken is not yet implemented.
TODO List:
- Implement AWS restXml protocol. Includes S3. Total service count 4.
- Implement sigv4a signing
- Implement jitter/exponential backoff
- Implement timeouts and other TODO's in the code
- Add option to cache signature keys
Compiler wishlist/watchlist:
- Merge PR to allow stripping -static
- comptime allocations so we can read files, etc (or is there another way)
