+# Rust Function Url Example
+
+This example uses [cargo lambda](https://www.cargo-lambda.info/) to build rust binaries and deploy them on a provided AL2 runtime
+
+NOTE: (cargo lambda relies on [zig](https://ziglang.org/), which it will prompt to install on first running a cargo lambda command)
+
+```sh
+cargo lambda build --release
+```
+
+you can also provide the architecture of choice
+
+```sh
+cargo lambda build --release --arm64
+# or
+cargo lambda build --release --x86-64
+```
+
+which can then be reflected in the `sst.config.ts`
+
+```ts
+const api = new sst.aws.Function("rust-api", {
+    architecture: "arm64", // or x86_64
+    ...
+});
+```
+
+by default, cargo lambda will build to a folder in `target/` called `lambda/`. The binary build will be called `bootstrap`, and it will be built in a sub folder which is the name of your binary.
+
+For example, a rust binary `src/bin/handlers/api.rs` will be built to `target/lambda/api/bootstrap`
+
+After building the binary, deploys can be done normally via `sst deploy --stage production`
+
+Other services can be orchestrated in a similar manner with cargo lambda, for example a cron:
+```ts
+new sst.aws.Cron('MyCron', {
+    schedule: 'cron(0 0 * * ? *)',
+    job: {
+        architecture: 'arm64',
+        runtime: 'provided.al2023',
+        handler: 'bootstrap',
+        bundle: 'target/lambda/my-cron',
+    }
+});
+```
+
+# GHA
+
+An example to deploy using github actions with `arm64` architecture, feel free to configure as needed
