Cargo plugin to easily query information from Cargo.toml files

Overview

This plugin helps querying information from a Cargo.toml file and can be used in shell scripts or CI/CD pipelines. The plugin accepts only one flag at a time and returns a single string with the requested value. Some queries like eq. keywords or authors return multiple values which get separated by line breaks (each value on a new line).

This plugin is inspired by cargo-edit and presents itself as a lightweight wrapper around cargo_toml
