# cargo verify-project

## NAME

cargo-verify-project - Check correctness of crate manifest

## SYNOPSIS

cargo verify-project [OPTIONS]

## DESCRIPTION

This command will parse the local manifest and check its validity. It emits a JSON object with the result. A successful validation will display:

{"success":"true"}

An invalid workspace will display:

{"invalid":"human-readable error message"}

## OPTIONS

### 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.

-q
--quiet

No output printed to stdout.

--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 in the current directory or any parent directory for the Cargo.toml file.

--frozen
--locked

Either of these flags requires that the Cargo.lock file is up-to-date. If the lock file is missing, or it needs to be updated, Cargo will exit with an error. The --frozen flag also prevents Cargo from attempting to access the network to determine if it is out-of-date.

These may be used in environments where you want to assert that the Cargo.lock file is up-to-date (such as a CI build) or want to avoid network access.

--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.

### Common Options

-h
--help

Prints help information.

-Z FLAG…​

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

## ENVIRONMENT

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

## Exit Status

0

The workspace is OK.

1

The workspace is invalid.

## EXAMPLES

1. Check the current workspace for errors:
