Crate mapped_file

Modules

• err
  Wrapping errno error types
• file
  Types for, and operations on file descriptors. Useful for mapping
• hugetlb
  Huge-page interface for MappedFile<T> and MemoryFile.
• ring
  mmap() based (regular or huge) page-sized ring-buffers over arbitrary files

Structs

• Anonymous
  Used for anonymous mappings with MappedFile.
• MappedFile
  A memory mapping over file T.
• TryNewError
  Error returned when mapping operation fails.

Enums

• Advice
  Advice to the kernel about how to load the mapped pages. These will control madvise().
• Flags
  Flags for mapping a file descriptor.
• Flush
  Options for flushing a mapping. These will control how the msync() is called.
• Perm
  Permissions for the mapped pages.

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
