Current executable size for the demo is 1.7M (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

WebIdentityToken is not yet implemented.

TODO List:

Bump to zig 0.11 and replace zFetch with std.http.Client
Implement sigv4a signing
Implement jitter/exponential backoff
Implement timeouts and other TODO's in the code
Add option to cache signature keys
Move CI to github actions based on gittea's implementation

Compiler wishlist/watchlist:

comptime allocations so we can read files, etc (or is there another way)
