Cargo-messages NPM

cargo-messages

cargo-messages: A streaming reader for JSON messages emitted from Cargo

This project was bootstrapped by create-neon.

Installing cargo-messages

Installing cargo-messages requires a supported version of Node and Rust.

You can install the project with npm. In the project directory, run:

$ npm install

This fully installs the project, including installing any dependencies and running the build.

Building cargo-messages

If you have already installed the project and only want to run the build, run:

$ npm run build

This command uses the cargo-cp-artifact utility to run the Rust build and copy the built library into ./index.node.

Exploring cargo-messages

After building cargo-messages, you can explore its exports at the Node REPL:

$ npm install
$ node
> require('.').hello()
"hello node"

Available Scripts

In the project directory, you can run:

`npm install`

Installs the project, including running npm run build.

`npm build`

Builds the Node addon (index.node) from source.

Additional cargo build arguments may be passed to npm build and npm build-* commands. For example, to enable a cargo feature:

npm run build -- --feature=beetle

`npm build-debug`

Alias for npm build.

`npm build-release`

Same as npm build but, builds the module with the release profile. Release builds will compile slower, but run faster.

`npm test`

Runs the unit tests by calling cargo test. You can learn more about adding tests to your Rust code from the Rust book.

Project Layout

The directory structure of this project is:

cargo-messages/
├── Cargo.toml
├── README.md
├── index.node
├── package.json
├── src/
|   └── lib.rs
└── target/

Cargo.toml

The Cargo manifest file, which informs the cargo command.

README.md

This file.

index.node

The Node addon—i.e., a binary Node module—generated by building the project. This is the main module for this package, as dictated by the "main" key in package.json.

Under the hood, a Node addon is a dynamically-linked shared object. The "build" script produces this file by copying it from within the target/ directory, which is where the Rust build produces the shared object.

package.json

The npm manifest file, which informs the npm command.

src/

The directory tree containing the Rust source code for the project.

src/lib.rs

The Rust library's main module.

target/

Binary artifacts generated by the Rust build.
