Struct Index 

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

A 64-bit versioned pointer.

Combines a 16-bit version ID with a 48-bit slot index. This ensures that an index pointing to an old version of a slot cannot be used after the slot has been advanced.

Implementations

impl Index

pub fn new(id: u16, slot_index: usize) -> Self

Creates a new versioned Index.

Arguments

• id - The 16-bit version identifier.
• slot_index - The physical offset in the data array (max 48 bits).

pub fn id(self) -> u16

Returns the 16-bit version identifier.

pub fn slot_index(self) -> usize

Returns the 48-bit physical slot index.

pub fn with_id(self, id: u16) -> Self

Returns a copy of the index with an updated version ID.

This is typically used during an advance operation to synchronize the index with a new Tag.

Trait Implementations

impl Clone for Index

fn clone(&self) -> Index

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Index

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

Formats the value using the given formatter.

impl From<Index> for u64

fn from(index: Index) -> Self

Converts to this type from the input type.

impl From<u64> for Index

fn from(raw_index: u64) -> Self

Converts to this type from the input type.

impl PartialEq for Index

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