This example shows how to deploy multiple binary rust project to AWS Lambda.

SST relies on the work of cargo lambda to build and deploy Rust Lambda functions.

What is special about the following file is that we are defining multiple binaries using the [[bin]] section in the Cargo.toml file.

Cargo.toml

[package]
name = "aws-lambda-rust-multi-bin"
version = "0.1.0"
edition = "2021"

[dependencies]
lambda_runtime = "0.13.0"
serde = { version = "1.0.217", features = ["derive"] }
serde_json = "1.0.138"
tokio = { version = "1", features = ["macros"] }
# -- please note ommited dependencies --

[[bin]]
name = "push"
path = "src/push.rs"

[[bin]]
name = "pop"
path = "src/pop.rs"

We then utilise the . syntax to specify the handler binary

sst.config.ts

new sst.aws.Function("push", {
  url: true,
  runtime: "rust",
  link: [bucket],
  handler: "./.push",
});
new sst.aws.Function("pop", {
  url: true,
  runtime: "rust",
  link: [bucket],
  handler: "./.pop",
});

sst.config.ts

const bucket = new sst.aws.Bucket("Bucket");
const push = new sst.aws.Function("push", {
  runtime: "rust",
  handler: "./.push",
  url: true,
  architecture: "arm64",
  link: [bucket],
});
const pop = new sst.aws.Function("pop", {
  runtime: "rust",
  handler: "./.pop",
  url: true,
  architecture: "arm64",
  link: [bucket],
});
