CARGO-INFO(1)               General Commands Manual              CARGO-INFO(1)

NAME
       cargo-info -- Display information about a package in the registry.
       Default registry is crates.io

SYNOPSIS
       cargo info [options] spec

DESCRIPTION
       This command displays information about a package in the registry. It
       fetches data from the package's Cargo.toml file and presents it in a
       human-readable format.

OPTIONS
   Info Options
       spec
           Fetch information about the specified package. The spec can be a
           package ID, see cargo-pkgid(1) for the SPEC format.  If the
           specified package is part of the current workspace, information
           from the local Cargo.toml file will be displayed.  If the
           Cargo.lock file does not exist, it will be created. If no version
           is specified, the appropriate version will be selected based on the
           Minimum Supported Rust Version (MSRV).

       --index index
           The URL of the registry index to use.

       --registry registry
           Name of the registry to use. Registry names are defined in Cargo
           config files
           <https://doc.rust-lang.org/cargo/reference/config.html>. If not
           specified, the default registry is used, which is defined by the
           registry.default config key which defaults to crates-io.

   Display Options
       -v, --verbose
           Use verbose output. May be specified twice for "very verbose"
           output which includes extra output such as dependency warnings and
           build script output.  May also be specified with the term.verbose
           config value
           <https://doc.rust-lang.org/cargo/reference/config.html>.

       -q, --quiet
           Do not print cargo log messages.  May also be specified with the
           term.quiet config value
           <https://doc.rust-lang.org/cargo/reference/config.html>.

       --color when
           Control when colored output is used. Valid values:

           o  auto (default): Automatically detect if color support is
               available on the terminal.

           o  always: Always display colors.

           o  never: Never display colors.

           May also be specified with the term.color config value
           <https://doc.rust-lang.org/cargo/reference/config.html>.

   Manifest Options
       --locked
           Asserts that the exact same dependencies and versions are used as
           when the existing Cargo.lock file was originally generated. Cargo
           will exit with an error when either of the following scenarios
           arises:

           o  The lock file is missing.

           o  Cargo attempted to change the lock file due to a different
               dependency resolution.

           It may be used in environments where deterministic builds are
           desired, such as in CI pipelines.

       --offline
           Prevents Cargo from accessing the network for any reason. Without
           this flag, Cargo will stop with an error if it needs to access the
           network and the network is not available. With this flag, Cargo
           will attempt to proceed without the network if possible.

           Beware that this may result in different dependency resolution than
           online mode. Cargo will restrict itself to crates that are
           downloaded locally, even if there might be a newer version as
           indicated in the local copy of the index.  See the cargo-fetch(1)
           command to download dependencies before going offline.

           May also be specified with the net.offline config value
           <https://doc.rust-lang.org/cargo/reference/config.html>.

       --frozen
           Equivalent to specifying both --locked and --offline.

   Common Options
       +toolchain
           If Cargo has been installed with rustup, and the first argument to
           cargo begins with +, it will be interpreted as a rustup toolchain
           name (such as +stable or +nightly).  See the rustup documentation
           <https://rust-lang.github.io/rustup/overrides.html> for more
           information about how toolchain overrides work.

       --config KEY=VALUE or PATH
           Overrides a Cargo configuration value. The argument should be in
           TOML syntax of KEY=VALUE, or provided as a path to an extra
           configuration file. This flag may be specified multiple times.  See
           the command-line overrides section
           <https://doc.rust-lang.org/cargo/reference/config.html#command-line-overrides>
           for more information.

       -C PATH
           Changes the current working directory before executing any
           specified operations. This affects things like where cargo looks by
           default for the project manifest (Cargo.toml), as well as the
           directories searched for discovering .cargo/config.toml, for
           example. This option must appear before the command name, for
           example cargo -C path/to/my-project build.

           This option is only available on the nightly channel
           <https://doc.rust-lang.org/book/appendix-07-nightly-rust.html> and
           requires the -Z unstable-options flag to enable (see #10098
           <https://github.com/rust-lang/cargo/issues/10098>).

       -h, --help
           Prints help information.

       -Z flag
           Unstable (nightly-only) flags to Cargo. Run cargo -Z help for
           details.

ENVIRONMENT
       See the reference
       <https://doc.rust-lang.org/cargo/reference/environment-variables.html>
       for details on environment variables that Cargo reads.

EXIT STATUS
       o  0: Cargo succeeded.

       o  101: Cargo failed to complete.

EXAMPLES
        1. Inspect the serde package from crates.io:

                cargo info serde

        2. Inspect the serde package with version 1.0.0:

                cargo info serde@1.0.0

        3. Inspect the serde package form the local registry:

                cargo info serde --registry my-registry
