Struct PageEntry 

pub struct PageEntry {
    pub pfn: u32,
    pub c: u8,
    pub dirty: bool,
    pub valid: bool,
}

One half of an entry — the even or odd page.

Fields

pfn: u32

Page frame number.

c: u8

Cache coherency attribute. Only 2 means uncached (UM Table 5-6, p. 145); 0, 1, 3, 4, 5, 6 and 7 are all cached, because the VR4300 has no coherency protocol and the VR4400’s finer encodings collapse.

dirty: bool

Dirty — meaning writable, not “has been written”. A store to a page with D clear raises TLB Modified.

valid: bool

Valid. Does not participate in matching; see the module docs.

Implementations

impl PageEntry

pub const fn uncached(self) -> bool

Is this page uncached?

Trait Implementations

impl Clone for PageEntry

fn clone(&self) -> PageEntry

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PageEntry

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PageEntry

fn default() -> PageEntry

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PageEntry

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PageEntry

fn eq(&self, other: &PageEntry) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for PageEntry

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for PageEntry

impl Eq for PageEntry

impl StructuralPartialEq for PageEntry
