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 and the concordium-rust-sdk crate.
The concordium-std crate is intended as the entry-point for development of smart contracts in Rust. It adds a number of helper macros and traits on top of the basic functionality available here.
The concordium-rust-sdk crate is for off-chain development and interaction with smart contracts.
std (enabled by default): Enables functionality that depends on the standard library.derive-serde: Enable serialization and deserialization via serde. Enables std as well.fuzz: Enable fuzzing via arbitrary. Enables derive-serde as well.sdk: Enable functionality only meant for concordium-rust-sdk. Enabling will change procedural macros to assume the context of the concordium-rust-sdk and enable functionality only meant for off-chain development.The minimum supported rust version is 1.56
