Minimize binary size due to structopt/clap?

[rom1v]

In a Rust app, I tried to replace my dirty manual command-line parsing by structopt.

It works well and the source code is far better. However, it makes my resulting binary 6× bigger. For instance the release+stripped version grows from 600K to 4M 1.4M, so at least 85% 57% of the binary is related to command-line parsing…

Are there any tips to reduce the final binary size?

EDIT: In fact, 4M is the non-stripped binary, the stripped is 1.4M (this is still bigger than 600K, but this makes a difference).

I think there is features in clap to limit the depedencies. Then, structopt have to forward the features.
