✨ cfg_table

A simple macro that expands to different values across compilation targets.

Panics

This macro will panic at runtime if no matching value is found.

Example

```rust

[macrouse] extern crate cfgtable;

let var = cfgtable! { [all(targetos = "freebsd", targetpointerwidth = "64", feature = "my-feature")] => 1337, // custom

// common platforms
win32 => 32,
win64 => 64,
linux32 => 32,
linux64 => 64,
macos32 => 32,
macos64 => 64,

// pointer widths
32 => 1985,
"32" => 1985,
64 => 2003,
"64" => 2003,

_ => 123, // default value if nothing matches, this must be at the bottom

};

cfg_table! { win32 => { println!("You're on Windows 32-bit!"); },

win64 => {
    println!("You're on Windows 64-bit!");
},

_ => {
    panic!("What the heck is a \"Linux\"?");
},

}; ```
