Crate mem

mem

A rather generic memory (block) interface. Use Mutexes if you need thread safety, this doesn’t provide any.

This crate is mainly for building emulators and such.

But.. why?!

Because abstraction is great. Well, this is really just an abstraction around byte addressable storage. Doesn’t have to be RAM, could be a file or even a block device. Or some sort of remote memory interface. Or a live memory debugger/editor for an emulator! Let your imagination go wild! :)

Modules

Error module y u do this???

Traits

MemoryBlock

Simple trait for a finite memory block.

MemoryBlock32be

Subtrait for 32 bit big-endian interface

MemoryBlock32le

Subtrait for 32 bit little-endian interface

MemoryCreator

Simple new(size) trait for backends.

MemoryMiddlewareCreator

Trait for a new function that wraps another memory block, returning one itself.

Functions

copy

Copy all of the src memory block to dst. Returns Ok(writtenbytes) to signify writtenbytes bytes have been copied, or Err(error) if some error happened during copying.

copy_at

Copy the contents of src at from to to to dst, starting at pos. Returns Ok(writtenbytes) to signify writtenbytes bytes have been copied, or Err(error) if some error happened during copying.

Type Aliases

Addr

Address type/size. Just a simple alias to usize for easier-to-read code. (In my opinion, obviously.) Originally, I wanted to make it use generics, but that got messy really quick.

Byte

Byte. Convenience alias.
