Serde is a framework for ***ser***ializing and ***de***serializing Rust data
structures efficiently and generically.
The `serde_core` crate contains Serde's trait definitions with **no support
for #\[derive()\]**.
In crates that derive an implementation of `Serialize` or `Deserialize`, you
must depend on the [`serde`] crate, not `serde_core`.
[`serde`]: https://crates.io/crates/serde
In crates that handwrite implementations of Serde traits, or only use them
as trait bounds, depending on `serde_core` is permitted. But `serde`
re-exports all of these traits and can be used for this use case too. If in
doubt, disregard `serde_core` and always use `serde`.
Crates that depend on `serde_core` instead of `serde` are able to compile in
parallel with `serde_derive` even when `serde`'s "derive" feature is turned on,
as shown in the following build timings.
