Struct memory_structs::VirtualAddress

pub struct VirtualAddress(/* private fields */);

A virtual memory address, which is a usize under the hood.

Implementations

impl VirtualAddress

pub fn new(addr: usize) -> Option<VirtualAddress>

Creates a new VirtualAddress, returning an error if the address is not canonical.

This is useful for checking whether an address is valid before using it. For example, on x86_64, virtual addresses are canonical if their upper bits (64:48] are sign-extended from bit 47, and physical addresses are canonical if their upper bits (64:52] are 0.

pub const fn new_canonical(addr: usize) -> VirtualAddress

Creates a new VirtualAddress that is guaranteed to be canonical.

pub const fn zero() -> VirtualAddress

Creates a new VirtualAddress with a value 0.

pub const fn value(&self) -> usize

Returns the underlying usize value for this VirtualAddress.

pub const fn page_offset(&self) -> usize

Returns the offset from the 4K page boundary specified by this `VirtualAddress.

For example, for the address 0xFFFF_1578, this will return 0x578, the least significant 12 bits (12:0] of this VirtualAddress.
