Traits

MapFlags

Any type implementing this trait can be passed to MappedFile<T>’s try_/new() method to provide flags directly for mmap(). Usually, the enum Flags should be used for this, but for HUGETLB configurations, or used-defined MAP_FIXED usages, it can be used on other types.

Functions

get_page_size

Get the current system page size
