Foundry Compilers

| Docs |

Originally part of ethers-rs as ethers-solc, Foundry Compilers is the compilation backend for Foundry.

ethers-rs's ethers-solc is considered to be in maintenance mode, and any fixes to it will also be reflected on Foundry Compilers. No action is currently needed from devs, although we heavily recommend using Foundry Compilers instead of ethers-solc.

Supported Rust Versions

Foundry Compilers will keep a rolling MSRV (minimum supported rust version) policy of at least 6 months. When increasing the MSRV, the new Rust version must have been released at least six months ago. The current MSRV is 1.83.0.

Note that the MSRV is not increased automatically, and only as part of a minor release.
