Enum CachePolicy 

pub enum CachePolicy {
    Empty,
    Count(usize),
    Tracked {
        max_size: usize,
        min_items: usize,
        mem_mode: MemMode,
    },
}

Variants

Empty

An empty cache (avoids acquiring locks etc so considered perf-free)

Count(usize)

The cache bounds the number of items it holds w/o tracking their inner size

Tracked

Items are tracked by size with a max_size limit overall. The cache will pass this limit if there are no more than min_items items in the cache. mem_mode determines whether items are tracked by bytes or by units

Fields

max_size: usize

min_items: usize

mem_mode: MemMode
