registry-backup 0.4.0-rc.4
Jonathan Strong <jstrong@shipyard.rs>
Download all .crate files from a registry server

USAGE:
    registry-backup [OPTIONS]

OPTIONS:
        --index-url <URL>
            URL of the registry index we are downloading .crate files from. The program expects that
            it will be able to clone the index to a local temporary directory; the user must handle
            authentication if needed

        --index-path <PATH>
            instead of an index url, just point to a local path where the index is already cloned

    -a, --auth-token <TOKEN>
            If registry requires authorization (i.e. "auth-required" key is set to `true` in the
            `config.json` file), the token to include using the Authorization HTTP header

    -o, --output-path <PATH>
            Directory where downloaded .crate files will be saved to
            
            [default: output]

        --overwrite-existing
            Download files when if .crate file already exists in output dir for a given crate
            version, and overwrite the existing file with the new one. Default behavior is to skip
            downloading if .crate file already exists

        --output-format <FORMAT>
            What format to use for the output filenames. Works the same as Cargo's registry syntax
            for the "dl" key in the `config.json` file in a reigstry index. See [Cargo
            docs](https://doc.rust-lang.org/cargo/reference/registries.html#index-format) for
            additional details. Not specifying this field is equivalent to specifying
            "{crate}/{version}/download", the default.
            
            The resulting path specified by the format should be relative; it will be joined with
            the --output-path. (i.e. it should not start with "/".)

    -U, --user-agent <USER_AGENT>
            Value of user-agent HTTP header
            
            [default: registry-backup/v0.4.0-rc.4]

    -R, --requests-per-second <INT>
            Requests to registry server will not exceed this rate
            
            [default: 100]

    -M, --max-concurrent-requests <INT>
            Independent of the requests per second rate limit, no more than
            `max_concurrent_requests` will be in flight at any given moment
            
            [default: 50]

    -c, --config-file <PATH>
            Specify configuration values using the provided TOML file, instead of via command line
            flags. The values in the config file will override any values passed as command line
            flags. See config.toml.sample for syntax of the config file

        --filter-crates <REGEX>
            Only crates with names that match --filter-crate regex will be downloaded

        --dry-run
            Don't actually download the .crate files, just list files which would be downloaded.
            Note: --requests-per-second and --max-concurrent-requests are still enforced even in
            --dry-mode!

    -h, --help
            Print help information

    -V, --version
            Print version information
