Cargo.toml OS Dependency for Crate

I have a rust project where i include the mysql-crate dependency and i want to have it os independent. So i tried: Cargo.toml ``` [package] name = "test" version = "0.1.0" authors = ["daMaex"] [dependencies] ws = "*" clap = "*" env_logger = "*" [target.'cfg(any(unix, macos))'.dependencies.mysql] version = "*" default-features = false features = ["socket"] [target.'cfg(windows)'.dependencies.mysql] version = "*" default-features = false features = ["pipe"] [features] default = [] ssl = [] ``` The error already happens with a minimal main: src/main.rs ``` fn main () { } ``` But the build fails. On macos/unix it always wants to compile the pipe and get's an unresolved import: ``` error[E0432]: unresolved import `std::os::windows::io::RawHandle` --> /home/user/.cargo/registry/src/github.com-1ecc6299db9ec823/named_pipe-0.2.2/src/lib.rs:38:5 | | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Could not find `windows` in `std::os` ``` and the same happens on Windows for the mysql crate itself: ``` error[E0432]: unresolved import `std::os::unix` --> C:\Users\user\.cargo\registry\src\github.com-1ecc6299db9ec823\mysql-7.1.2\src\io.rs:24:5 | 24 | use std::os::unix as unix; | ^^^^^^^^^^^^^^^^^^^^^ no `unix` in `std::os` ``` So my question is, how do i handle the OS-Dependency in this case?
