Enum Caching 

#[non_exhaustive]
pub enum Caching {
    Normal,
    Mmio,
    WriteCombine,
}

Available on crate feature full only.

The caching strategy to use for the mapping.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Normal

The fastest cache strategy. This should be used for the majority of mappings.

Mmio

All access bypasses the cache. This should only be used when preserving the exact sequence of memory accesses is important.

WriteCombine

Reads bypass the cache. Small sequential writes are buffered to be written in a single large access.
