Struct Round 

pub struct Round { /* private fields */ }

A unique identifier combining epoch and view for a consensus round.

Round provides a total ordering across epoch boundaries, where rounds are ordered first by epoch, then by view within that epoch.

Implementations

impl Round

pub const fn new(epoch: Epoch, view: View) -> Self

Creates a new round from an epoch and view.

pub const fn zero() -> Self

Returns round zero, i.e. epoch zero and view zero.

pub const fn epoch(self) -> Epoch

Returns the epoch of this round.

pub const fn view(self) -> View

Returns the view of this round.

Trait Implementations

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 Default for Round

fn default() -> Round

Returns the “default value” for a type.

impl Display for Round

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

Formats the value using the given formatter.

impl EncodeSize for Round

fn encode_size(&self) -> usize

Returns the encoded size of this value (in bytes).

impl Epochable for Round

fn epoch(&self) -> Epoch

Returns the epoch associated with this object.

impl From<(Epoch, View)> for Round

fn from((epoch, view): (Epoch, View)) -> Self

Converts to this type from the input type.

impl From<Round> for (Epoch, View)

fn from(round: Round) -> Self

Converts to this type from the input type.

impl Hash for Round

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 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 Read for Round

type Cfg = ()

The Cfg type parameter allows passing configuration during the read process. This is crucial for safely decoding untrusted data, for example, by providing size limits for collections or strings.

fn read_cfg(buf: &mut impl Buf, _cfg: &Self::Cfg) -> Result<Self, Error>

Reads a value from the buffer using the provided configuration cfg.

impl Viewable for Round

fn view(&self) -> View

Returns the view associated with this object.

impl Write for Round

fn write(&self, buf: &mut impl BufMut)

Writes the binary representation of self to the provided buffer buf.

impl Copy for Round

impl Eq for Round
