Struct dpdk_unix::memory_information::VirtualAddress

pub struct VirtualAddress(_);

A virtual address.

This is the same as the value returned from malloc(), a *mut T pointer, a &T reference, etc.

No checks are made for its validity.

Methods

impl VirtualAddress

pub fn offset_from_start_of_page(self) -> usize

Relative offset from the start of the system page containing this virtual address.

May be zero, but will always be less than the system page size.

pub fn first_address_in_page(self) -> Self

The address of the page which contains this physical address. May be the same value.

pub fn virtual_addresses_to_physical_addresses<HVA: HasVirtualAddress>(
    have_virtual_addresses: impl Iterator<Item = HVA>,
    physical_address_user: impl FnMut(HVA, Self, PhysicalAddress)
)

This function will translate virtual addresses to physical addresses.

Before using this function, the memory reference by a virtual address should have been mlock()'d.
