Utilities for working with substrate metadata for `subxt`
|
|
|
|
```
|
|
USAGE:
|
|
subxt <SUBCOMMAND>
|
|
|
|
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 <format> the format of the metadata to display: `json`, `hex` or `bytes` [default: json]
|
|
--url <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 <file>
|
|
the path to the encoded metadata file
|
|
|
|
--url <url>
|
|
the url of the substrate node to query for metadata for codegen
|
|
|
|
```
