cargo-locate-project - Print a JSON representation of a Cargo.toml file's location


cargo locate-project [options]


This command will print a JSON object to stdout with the full path to the Cargo.toml manifest.


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.
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.
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
Overrides a Cargo configuration value.
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.
