cargo-doc:tldr:6457f

This command is using the Cargo package manager, which is a build tool for Rust programming language projects. The specific command cargo doc --open --offline --package ${package} is used to generate and open the documentation for a particular package in your project.

Here is a breakdown of the command:

• cargo doc is the base command to generate documentation for Rust projects.
• --open is an optional flag that opens the generated documentation in a web browser after the generation process is complete.
• --offline is an optional flag that tells Cargo to use locally cached crates instead of fetching them from the internet during the documentation generation process. This can be useful if you want to generate documentation without an internet connection.
• --package ${package} is an optional flag used to specify the package for which you want to generate documentation. The ${package} variable should be replaced with the actual name of the package. By default, if no package is specified, documentation for all packages in the project is generated.

In summary, this command generates documentation for the specified package and opens it in a web browser. If provided, it also uses locally cached crates and does not fetch any new dependencies from the internet.
