concordium-contracts-common-0.3.0 has been yanked.
This library provides the core API that can be used to write smart contracts for the Concordium blockchain in the Rust programming language. It aims to provide safe wrappers around the core primitives exposed by the chain and accessible to smart contracts.
The functionality in this library is re-exported via the concordium-std
crate, which is intended as the entry-point for development of smart
contracts in Rust. concordium-std
adds a number of helper macros and
traits on top of the basic functionality available here.
