Modules

Wrapping errno error types

Types for, and operations on file descriptors. Useful for mapping

Huge-page interface for MappedFile<T> and MemoryFile.

mmap() based (regular or huge) page-sized ring-buffers over arbitrary files

Structs

Used for anonymous mappings with MappedFile.

A memory mapping over file T.

Error returned when mapping operation fails.

Enums

Advice to the kernel about how to load the mapped pages. These will control madvise().

Flags for mapping a file descriptor.

Options for flushing a mapping. These will control how the msync() is called.

Permissions for the mapped pages.

Traits

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
