Struct LogPosition 

pub struct LogPosition {
    pub term: Term,
    pub index: LogIndex,
}

Log position (Term and LogIndex).

A LogPosition uniquely identifies a LogEntry stored within a cluster.

Fields

term: Term

Term of the log entry.

index: LogIndex

Index of the log entry.

Implementations

impl LogPosition

pub const ZERO: Self

The initial log position (Term::ZERO and LogIndex::ZERO).

pub const INVALID: Self

An invalid log position.

pub const fn is_invalid(self) -> bool

Returns true if this position is equal to LogPosition::INVALID.

Trait Implementations

impl Clone for LogPosition

fn clone(&self) -> LogPosition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LogPosition

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

Formats the value using the given formatter.

impl Hash for LogPosition

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 Ord for LogPosition

fn cmp(&self, other: &LogPosition) -> 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,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for LogPosition

fn eq(&self, other: &LogPosition) -> 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 PartialOrd for LogPosition

fn partial_cmp(&self, other: &LogPosition) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
