Lintspec is a command-line utility (linter) that checks the completeness and validity of NatSpec doc-comments in Solidity code. It is focused on speed and ergonomics and aims to improve the user experience over existing solutions.
In this short article, we go over a setup to distribute AWS Lambda endpoints written in the Rust programming language through Docker images instead of a zipped binary. This technique leverages the power of Cargo Lambda and multi-stage Docker builds.
Differential testing allows to compare implementations and is especially useful in Solidity, where optimizations are frequently made by replacing code with low-level YUL instructions. By leveraging the fast startup times and low footprint of Rust binaries via FFI, Foundry allows to efficiently integrate diff testing in Solidity projects.
