Utilities for working with substrate metadata for subxt

``` USAGE: subxt

FLAGS: -h, --help Prints help information

-V, --version
        Prints version information

SUBCOMMANDS: codegen Generate runtime API client code from metadata help Prints this message or the help of the given subcommand(s) metadata Download metadata from a substrate node, for use with subxt codegen ```

Metadata

Use to download metadata for inspection, or use in the subxt macro. e.g.

subxt metadata -f bytes > metadata.scale

``` USAGE: subxt metadata [OPTIONS]

OPTIONS: -f, --format the format of the metadata to display: json, hex or bytes [default: json] --url the url of the substrate node to query for metadata [default: http://localhost:9933] ```

Codegen

Use to invoke the subxt-codegen crate which is used by subxt-macro to generate the runtime API and types. Useful for troubleshooting codegen as an alternative to cargo expand, and also provides the possibility to customize the generated code if the macro does not produce the desired API. e.g.

subxt codegen | rustfmt --edition=2018 --emit=stdout

``` USAGE: subxt codegen [OPTIONS]

OPTIONS: -f, --file the path to the encoded metadata file

    --url <url>
        the url of the substrate node to query for metadata for codegen
