How to use the command 'cargo pkgid' (with examples)
The cargo pkgid command is a command provided by the Cargo package manager for Rust. This command is used to print the fully qualified package ID specifier for a package or dependency in the current workspace. The package ID specifier includes both the package’s name and its version. It can be useful for tracking and identifying packages within a Rust project.
Use case 1: Print the fully qualified package specification for the current project
Code:
cargo pkgid
Motivation: Understanding the fully qualified package specification for the current project can be helpful for a variety of reasons. It allows developers to easily identify the specific version of the project they are working on and quickly verify if any dependencies have been updated.
Explanation:
In this use case, the cargo pkgid command is executed without any arguments. This command will print the fully qualified package ID specifier for the current project in the current workspace. The current project refers to the one containing the Cargo.toml file in the current directory.
Example output:
myproject v0.1.0 (/path/to/myproject)
Use case 2: Print the fully qualified package specification for the specified package
Code:
cargo pkgid partial_pkgspec
Motivation: Sometimes, you may need to print the fully qualified package specification for a specific package or dependency within your Rust workspace. This can be useful for checking the version or resolving potential version conflicts.
Explanation:
In this use case, the cargo pkgid command is executed with an additional argument partial_pkgspec. This argument specifies the partial package name or dependency name for which you want to print the fully qualified package specification. The partial_pkgspec can be either the full name or a partial name that can uniquely identify the package or dependency.
Example output:
mydependency v1.0.0 (/path/to/mydependency)
Conclusion:
The cargo pkgid command is a powerful tool provided by Cargo to print the fully qualified package ID specifier for packages and dependencies in a Rust workspace. Whether you want to identify the fully qualified package specification for the current project or for a specific package, cargo pkgid makes it easy to retrieve this information. This command is useful for managing and tracking packages within a Rust project.
