Rust Lambda API

This repository contains a RESTful API implemented in Rust, which performs Create and Read operations for a "Course" entity. Each Course has three attributes:

• course_id
• course_name
• course_category

---

Development

1. Write/Edit Rust code in the src/bin folder

2. Format the Rust code using :

   cargo fmt 

3. Compile binaries of the Rust Code :

   cargo lambda build --release

---

Deployment

The infrastructure is provisioned using AWS CDK.

To deploy the API, follow these steps:

1. Navigate to the deploy directory:

   cd deploy

2. Install the required dependencies:

   npm install

3. Generate the CloudFormation template using CDK:

   cdk synth

4. Deploy the infrastructure using CDK:

   cdk deploy

This will create the necessary AWS resources, including:

• Three Lambdas: getById, getByCategory, and create, each with its own Function URL.
• One DynamoDB table: CourseTable.
• One API Gateway with three endpoints: /get, /getByCategory, and /create.

The Lambdas are implemented using three separate Rust handlers, each compiled into a binary.

Prerequisites

Before developing/deploying the API, make sure you have the following prerequisites:

• Rust compiler installed on your system.
• AWS CDK installed.
• Cargo Lambda installed.
