Struct ManualPageCounter

pub struct ManualPageCounter { /* private fields */ }

An specialized handler of the page counter that tracks both the physical and the logical page counter.

Implementations

impl ManualPageCounter

pub fn new() -> Self

Create a new fast page counter, starting at 1.

pub fn physical(&self) -> NonZeroUsize

Get the current physical page counter state.

pub fn logical(&self) -> usize

Get the current logical page counter state.

pub fn visit( &mut self, engine: &mut Engine<'_>, page: &Frame, ) -> SourceResult<()>

Advance past a page.

pub fn step(&mut self)

Step past a page boundary.

Trait Implementations

impl Clone for ManualPageCounter

fn clone(&self) -> ManualPageCounter

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ManualPageCounter

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

Formats the value using the given formatter.

impl Default for ManualPageCounter

fn default() -> Self

Returns the “default value” for a type.

impl Hash for ManualPageCounter

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ManualPageCounter

fn eq(&self, other: &ManualPageCounter) -> 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.
