subxt-cli
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 the runtime API and types. Useful
for troubleshooting codegen as an alternative to cargo expand, and also provides the possibility of customizing 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
