cargo-pkgid

Print a fully qualified package specification

TLDR

Show package ID for current package

$ cargo pkgid

Show package ID for a dependency

$ cargo pkgid [serde]

Show package ID for a specific version of a dependency

$ cargo pkgid [[email protected]]

Show package ID using a specific Cargo.toml

$ cargo pkgid --manifest-path [path/to/Cargo.toml] [serde]

Show package ID from a URL

$ cargo pkgid [https://github.com/rust-lang/crates.io-index#serde]

cargo pkgid prints the fully qualified package ID specification for a package in the dependency graph. The output includes the source URL, package name, and version in a canonical format that can be used with other Cargo commands like `cargo update -p`.This command is primarily useful when multiple versions of the same package exist in the dependency tree and disambiguation is needed. It accepts partial specifications such as just the name or name with version, and resolves them against the lockfile. The Cargo.lock file must exist and dependencies must be fetched before this command can be used.

PARAMETERS

-p, --package spec

Package to query

--manifest-path path

Path to Cargo.toml

--locked

Assert that the exact same dependencies and versions are used as when the existing Cargo.lock was generated

--offline

Prevent Cargo from accessing the network

--frozen

Equivalent to specifying both --locked and --offline

--color when

Control colored output: auto (default), always, or never

-v, --verbose

Verbose output. Specify twice for very verbose output.

-q, --quiet

Do not print cargo log messages

CAVEATS

Errors if specification is ambiguous. Add version qualifier to disambiguate multiple versions. Requires lockfile and fetched dependencies.
