Suggestion: derive Cargo feature

[RReverser]

Nowadays, in serde the recommended way to import derives is to use serde = { version = ..., features = ["derive"] } in Cargo.toml. It takes care of reexporting the macros, to instead of writing

use serde::{Serialize, Deserialize};
use serde_derive::{Serialize, Deserialize};

to import both traits and derives you can just write

use serde::{Serialize, Deserialize};

Would it be possible to make serde_state have the same feature so that derives would be automatically included under corresponding trait names?

This may be fixed if we do another merge from serde upstream, though that can be quite annoying at times.

@Marwes Is there any way to detach them / reuse serde bits via public APIs instead?

[Marwes]

No, this is basically serde_derive but modified to thread a state argument through. serde_derive itself does not (and could not, without seriously invasive changes) expose an API for this.

They do have serde_derive_internals - that API is not stable either, but maybe sufficient? Just thinking of ways to make upgrades a bit easier.
