This is a semantics for a subset of Rust + and a subset of the MultiversX extensions that is easy to implement.
As an example, a lot of Rust features are not supported, or have limited support
(e.g., structs, inheritance, modules, imports).
Also, this semantics relies on top-level traits being annotated with
#[ulm::contract], and allows calls to methods declared in these
traits.
You must have ulm and evm-semantics checked out as sibling directories
(i.e. ../ulm and ../evm-semantics).
Build the semantics:
make build-ulm -j3
Preprocess and convert a contract to bytes:
compilation/prepare-contract.sh \
tests/ulm-contracts/erc_20_token.rs \
.build/compilation/erc_20_token.preprocessed.kore
