Rust compilation error based on potentially broken serde API

[homer6]

I ran into this error with the latest version of lsh-rs:

   Compiling lsh-rs v0.4.0

Some errors have detailed explanations: E0432, E0433.

I was running the latest serde:

serde = { version = "1.0.187", features = ["derive"] }

Based on this post, I downgraded to serde 1.0.118 and it compiled:

serde = { version = "=1.0.118", features = ["derive"] }

Maybe we need to update lsh-rs to be compatible with their new API?

This is fixed in the repo but still broken in crates.io.
