Struct RegisterState 

pub struct RegisterState { /* private fields */ }

Internal state of the ranked register as stored in FoundationDB

Tracks the maximum read and write ranks alongside the current value. Private fields enforce invariants through the algorithm module.

Implementations

impl RegisterState

pub fn max_read_rank(&self) -> Rank

Returns the highest rank that has performed a read

pub fn max_write_rank(&self) -> Rank

Returns the highest rank that has successfully written

pub fn value(&self) -> Option<&[u8]>

Returns the current value, if any

Trait Implementations

impl Clone for RegisterState

fn clone(&self) -> RegisterState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RegisterState

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

Formats the value using the given formatter.

impl Default for RegisterState

fn default() -> RegisterState

Returns the “default value” for a type.

impl PartialEq for RegisterState

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