Rust crates are published to crates.io and can be found on docs.rs with the "solana-" prefix.
Some important crates:
solana-program— Imported by programs running on Renec, compiled to BPF. This crate contains many fundamental data types and is re-exported from
solana-sdk, which cannot be imported from a Renec program.
solana-sdk— The basic off-chain SDK, it re-exports
solana-programand adds more APIs on top of that. Most Renec programs that do not run on-chain will import this.
solana-client— For interacting with a Renec node via the JSON RPC API.
renec-cli-config— Loading and saving the Solana CLI configuration file.
solana-clap-utils— Routines for setting up a CLI, using
clap, as used by the main Renec CLI.
