Crate memory_structs

This crate contains basic types used for memory management.

The types of interest are divided into three categories:

1. addresses: VirtualAddress and PhysicalAddress.
2. “chunk” types: Page and Frame.
3. ranges of chunks: PageRange and FrameRange.

Structs

• Frame
  A Frame is a chunk of physical memory aligned to a page boundary (default 4KiB) given by the P parameter.
• FrameRange
  A range of Frames that are contiguous in physical memory.
• Page
  A Page is a chunk of virtual memory aligned to a page boundary (default 4KiB) given by the P parameter.
• Page1G
  Marker struct used to indicate a page size of 1GiB.
• Page2M
  Marker struct used to indicate a page size of 2MiB.
• Page4K
  Marker struct used to indicate the default page size of 4KiB.
• PageRange
  A range of Pages that are contiguous in virtual memory.
• PhysicalAddress
  A physical memory address, which is a usize under the hood.
• VirtualAddress
  A virtual memory address, which is a usize under the hood.

Enums

• MemChunkSize
  Enum used to indicate the size of a page or frame.
• MemoryState
  The possible states that a range of exclusively-owned pages or frames can be in.

Traits

• PageSize
  Trait that represents the size of a page or frame, i.e., for normal or huge pages.
