serde_core has just been released. Crates that don't depend on serde derive macros should use it instead of
serde, as it speeds up compile times by having the build for the crate itself be independent fromserde-derive(in case it were to be enabled by some other crate). See the serde_core docs for more info.While at it this also removes uses of
serde::serde_if_integer128!, since all supported Rust versions in modern versions of serde support 128 bit integers https://github.com/serde-rs/serde/blob/3f6925125bae7837d918da63f2dba6efabad8dec/serde/src/integer128.rs.On my Ryzen 5 5500U, the clean release build time for just
csvin a project containingcsv, andserdewith thederivefeature enabled, went from 6.97s to 4.06s.
