Metrics can be printed on screen or exported as different output formats through rust-code-analysis-cli.

For each function space, rust-code-analysis computes the list of metrics described above. At the end of this process, rust-code-analysis-cli dumps the result formatted in a certain way on the screen. The command used to print the metrics is the following one:

rust-code-analysis-cli -m -p /path/to/your/file/or/directory

The -p option represents the path to a file or a directory. If a directory is passed as input, rust-code-analysis-cli computes the metrics for each file contained in it.

Different output formats can be used to export metrics:

• Cbor
• Json
• Toml
• Yaml

Json and Toml can also be exported pretty-printed.

For example, if you want to export metrics as a json file, run:

rust-code-analysis-cli -m -O json -o /output/path -p /path/to/your/file/or/directory

The -O option allows you to choose the output format. It supports only these values: cbor, json, toml, yaml.

The -o option is used to specify the path where your file will be saved. It accepts only paths. The filename of your output file is the same as your input file plus the extension associated to the format. When this option is not given, the output is printed on shell.

As we said before, Json and Toml can be exported as pretty-printed. To do so, the --pr option is used. In the case below, the pretty-printed json output will be printed on shell:

rust-code-analysis-cli -m -O json --pr -p /path/to/your/file/or/directory
