Struct VAddr

pub struct VAddr<Meta: VmMeta>(/* private fields */);

虚拟地址。

Implementations

impl<Meta: VmMeta> VAddr<Meta>

pub const fn new(value: usize) -> Self

将一个地址值转换为虚拟地址意味着允许虚存方案根据实际情况裁剪地址值。 超过虚址范围的地址会被裁剪。

pub const fn val(self) -> usize

虚地址值。

pub const unsafe fn as_ptr<T>(self) -> *const T

将虚地址转化为任意指针。

Safety

调用者需要确保虚地址在当前地址空间中。

pub unsafe fn as_mut_ptr<T>(self) -> *mut T

将虚地址转化为任意可变指针。

Safety

调用者需要确保虚地址在当前地址空间中。

pub const fn floor(self) -> VPN<Meta>

包括这个虚地址最后页的页号。

pub const fn ceil(self) -> VPN<Meta>

不包括这个虚地址的最前页的页号。

pub const fn offset(self) -> usize

页内偏移。

impl<Meta: Ord + VmMeta> Ord for VAddr<Meta>

fn cmp(&self, other: &VAddr<Meta>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,
