Tracking issue for deprecating serde_macros

[dtolnay]

Serde_derive has many advantages over serde_macros and a short list of disadvantages which are within sight of being eliminated.

Here are the things that need to happen before serde_derive can replace serde_macros:

• Documentation Document how to use serde_derive serde-rs.github.io#21
• Macros 1.1 bug Reordering of attributes passed to rustc_macro_derive rust-lang/rust#36211 (we have a workaround)
• Compilation time Remove dependency on Syntex #540
• Dependency nightmare (depending on how we resolve compile time) Cargo features need to be additive #543

Nice-to-haves but not blockers:

• Error spans are misleading Error spans in macros 1.1 rust-lang/rust#36218

Serde_derive has many advantages over serde_derive

Shouldn't that be "Serde_derive has many advantages over serde_macros" or something?

Fixed, thanks.

I released 0.8.10 announcing the deprecation.

I made a users.rust-lang.org post as well.
