Macro config_target_pointer_width_64 

macro_rules! config_target_pointer_width_64 {
    ($($item:item)*) => { ... };
}

Generates code only compiled when the target pointer width is 64 bits.

Example

use orengine_utils::{config_target_pointer_width_16, config_target_pointer_width_32, config_target_pointer_width_64};

config_target_pointer_width_64! {
    const VALUE: usize = 64;
}

config_target_pointer_width_32! {
    const VALUE: usize = 32;
}

config_target_pointer_width_16! {
    const VALUE: usize = 16;
}

#[cfg(target_pointer_width = "64")]
const SHOULD_BE: usize = 64;

#[cfg(target_pointer_width = "32")]
const SHOULD_BE: usize = 32;

#[cfg(target_pointer_width = "16")]
const SHOULD_BE: usize = 16;

assert_eq!(VALUE, SHOULD_BE);
