Using Scarb as a library deprecated

WARNING

Scarb crate is scheduled for deprecation in unspecified future. It is advised not to use it in new projects.

The combination of calling scarb command with the --json flag, and the scarb metadata command should cover all use cases for communicating with Scarb from outside world.

WARNING

Scarb is not being published to crates.io anymore. Use Scarb via Git reference in your Cargo.toml.

Scarb is a Rust crate which can be used as a regular library in Rust applications. We publish each release of Scarb to crates.io, the official package registry for Rust.

This crate serves as an API for writing custom extensions for Scarb. It is not recommended to link to Scarb in regular unrelated applications, for this it is preferred to interact with Scarb binary.
