I would like to self-nominating my dashu crate. This is not the first time to nominate it, but last time it unfortunately didn't get enough likes.
dashu is a Rust-native ergonomic library set of arbitrary precision numbers. It's a full alternative to the GMP + MPFR + MPC set, and its dashu-int is more efficient and feature complete compared to the de-facto standard num-bigint.
Please checkout my recent post on it if you are interested in it: Dashu is approaching v1.0: it's a full alternative to GMP+MPFR+MPC, and it's now more optimized
I hope the crate can obtain more attention and usage by make it mentioned in TWiR, because its v1.0 version will be landed by the end of the year. I hope I can get a good API design before commit its API as stable by v1.0.
