Struct AddressContext 

pub struct AddressContext {
    pub va: Va,
    pub root: Pa,
}

A complete address context within a system for virtual to physical address translation.

In virtual machine introspection (VMI) and memory analysis, it’s often necessary to work with addresses from different processes or memory spaces. The AddressContext struct encapsulates both a virtual address and the corresponding translation root, providing all the information needed to accurately translate the virtual address to a physical address.

The AddressContext is commonly used as an input to memory access or translation functions in VMI tools, ensuring that the correct translation context is applied for each memory operation.

Example

let user_space_address = AddressContext {
    va: Va(0x7ffe0000),
    root: Pa(0x1000000),  // CR3 value for a specific process
};

let kernel_space_address = AddressContext {
    va: Va(0xfffff80000000000),
    root: Pa(0x2000000),  // CR3 value for kernel space
};

// These contexts can then be used in memory operations
// vmi.read(user_space_address, &mut buffer)?;
// vmi.translate_address(kernel_space_address)?;

Fields

va: Va

The virtual address.

root: Pa

The translation root, typically the base of the page table hierarchy (e.g., CR3 in x86).
