A library that provides an implementation of a Wasm execution engine to suit Concordium's needs. In particular it implements - parsing and validation of Wasm modules, where validation is according to Wasm core 1 spec with additional restrictions necessary for blockchain use. - a compiler to a lower-level format that is easier to execute - an interpreter - utilities for storing and loading processed code
This is a low-level library that implements only the Wasm parts of execution.
The companion library concordium-smart-contract-engine provides an integration
of the Wasm together with state management, and provides higher-level functions
for executing smart contract entrypoints.
This crate follows semantic versioning guidelines. Change in minimum supported rust version will be accompanied by a minor version increase.
