Struct Round 

pub struct Round(pub Option<u32>);

A round number (or None if the round is nil).

This type represents a consensus round number. A round can be either a specific round number or nil (None), which represents a special state in the consensus protocol.

Example

let round = Round::new(5); // Round 5
let nil_round = Round::nil(); // Nil round

Tuple Fields

0: Option<u32>

Implementations

impl Round

pub fn new(round: u32) -> Self

Create a new round with the given round number.

pub fn nil() -> Self

Create a nil round.

pub fn as_u32(&self) -> Option<u32>

Get the round number as a u32, if it’s not nil.

Trait Implementations

impl Add<u32> for Round

type Output = Round

The resulting type after applying the + operator.

fn add(self, rhs: u32) -> Self::Output

Performs the + operation.

impl Clone for Round

fn clone(&self) -> Round

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Round

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Round

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Round

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

Formats the value using the given formatter.

impl From<Round> for Round

fn from(value: Round) -> Self

Converts to this type from the input type.

impl From<Round> for Round

fn from(value: Round) -> Self

Converts to this type from the input type.

impl From<u32> for Round

fn from(round: u32) -> Self

Converts to this type from the input type.

impl Ord for Round

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

fn eq(&self, other: &Round) -> 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 Round

fn partial_cmp(&self, other: &Round) -> 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.

impl Serialize for Round

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Sub<u32> for Round

type Output = Round

The resulting type after applying the - operator.

fn sub(self, rhs: u32) -> Self::Output

Performs the - operation.

impl Eq for Round
