The Webb Core SDK for Rust
Use the subxt-cli
tool to download the metadata for your target runtime from a node.
- Install:
cargo install subxt-cli
- To Save the metadata of
tangle
: Run the release build of thetangle
node, then on another terminal run:
subxt metadata -f bytes > ./metadata/tangle-runtime.scale
Same goes for any future runtimes.
Note: This defaults to querying the metadata of a locally running node on the default
http://localhost:9933/
. If querying a different node then themetadata
command accepts a--url
argument.
- Generating the rust code from the metadata:
cargo build --features generate-substrate
Tip: See the build.rs file to see how everything is being generated.
- Update any contracts inside the contracts directory.
- Run
cargo build --features generate-contracts
Tip: See the build.rs file to see how everything is being generated.
- Install Nix
- Enable flakes (if you haven't already)
- Run
nix develop
to enter a shell with all the dependencies installed
Additionally, if you have direnv installed, you can run direnv allow
to automatically enter the shell whenever you enter the directory.
This crate uses #![deny(unsafe_code)]
to ensure everything is implemented in
100% Safe Rust.
