Crate region

A library for manipulating memory regions

This crate provides several functions for handling memory pages and regions. It is implemented using platform specific APIs. The library is relatively bare metal.

Not all OS specific quirks are abstracted away. For instance; some OSs enforce memory pages to be readable whilst other may prevent pages from becoming executable (i.e DEP).

Usage

This crate is on crates.io and can be used by adding region to your dependencies in your project's Cargo.toml.

[dependencies]
region = "0.0.1"

and this to your crate root:

extern crate region;

Modules
