Print the full path to the `Cargo.toml` manifest of the current project.


Print the JSON object to stdout with full path to the Cargo.toml manifest

$ cargo locate-project

Print the project path in the specified format
$ cargo locate-project --message-format [plain|json]

Print the Cargo.toml manifest located at the root of the workspace as opposed to the current workspace member
$ cargo locate-project --workspace


cargo locate-project [options]


This command will print a JSON object to stdout with the full path to the manifest. The manifest is found by searching upward for a file named Cargo.toml starting from the current working directory.

If the project happens to be a part of a workspace, the manifest of the project, rather than the workspace root, is output. This can be overridden by the --workspace flag. The root workspace is found by traversing further upward or by using the field package.workspace after locating the manifest of a workspace member.



Locate the Cargo.toml at the root of the workspace, as opposed to the current workspace member.

Display Options

--message-format fmt

The representation in which to print the project location. Valid values:

·json (default): JSON object with the path under the key “root”.

·plain: Just the path.

-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 <>.

-q, --quiet

Do not print cargo log messages. May also be specified with the term.quiet config value <>.

--color when

Control when colored output is used. Valid values:

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

·always: Always display colors.

·never: Never display colors.

May also be specified with the term.color config value <>.

Manifest Options

--manifest-path path

Path to the Cargo.toml file. By default, Cargo searches for the Cargo.toml file in the current directory or any parent directory.

Common Options


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 <> 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 <> for more information.


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 <> and requires the -Z unstable-options flag to enable (see #10098 <>).

-h, --help

Prints help information.

-Z flag

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


See the reference <> for details on environment variables that Cargo reads.
