Enum CachePolicy 

pub enum CachePolicy {
    Auto,
    Always,
    Never,
}

Whether the bundle gets a generated /etc/ld.so.cache.

The loader searches a fixed set of directories plus whatever the objects themselves declare; everything else it knows comes from the cache, and a bundle has no ldconfig to build one. CachePolicy::Auto therefore writes a cache exactly when the plan contains something the loader would otherwise fail to find.

Variants

Auto

Always

Never
