Installing Wasm Target for Rust

This section walks you through the process of installing Wasm target for Rust.

To build and deploy Rust contracts on the blockchain, install the WebAssembly (Wasm) target for Rust using Rustup. Wasm enables secure and efficient execution of Rust code on various blockchain platforms. Follow these steps:

  1. Open your terminal.

  2. To install Wasm, run the following command in your terminal:

rustup target add wasm32-unknown-unknown

Here's a breakdown of the command:

  • target: Manages configurations for compiling Rust code for specific platforms.

  • add: Adds a new target.

  • wasm32-unknown-unknown: Identifies the WebAssembly target, indicating compilation of Rust code for WebAssembly without specifying a particular platform or version.

  1. After running the command, you'll see an output similar to the following in your terminal:

This indicates that the required standard library 'rust-std' for your Wasm target 'wasm32-unknown-unknown' has been successfully downloaded and installed. This enables you to compile Rust code for WebAssembly.

  1. The following components will be installed on your local machine:

    • Wasm toolchain: This includes the compiler, linker, and other necessary tools for compiling and building Rust code specifically for WebAssembly (Wasm).

    • Wasm standard library (rust-std): This library provides essential functionalities and structures for your Rust code to operate within the Wasm environment.
