Before:

$ cargo +nightly build --no-default-features --features unstable
   Compiling serde v1.0.177 (/srv/mpn/serde/serde)
error[E0432]: unresolved import `std_error`
   --> serde/src/de/mod.rs:134:9
134 | pub use std_error::Error as StdError;
    |         ^^^^^^^^^ maybe a missing crate `std_error`?

After:

$ cargo +nightly build --no-default-features --features unstable
   Compiling serde v1.0.177 (/srv/mpn/serde/serde)
    Finished dev [unoptimized] target(s) in 1.28s

Note that unstable and non-std tests are still failing.

Issue: #812

Thanks for the PR!

Unconditionally using std_error makes the rendered documentation less clear. I opened #2541 with a different implementation that follows the one of serde::ser::StdError.
