Struct Participant 

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

Re-export Participant from commonware_utils for convenience. Represents a participant/validator index within a consensus committee.

Participant indices are used to identify validators in attestations, votes, and certificates. The index corresponds to the position of the validator’s public key in the ordered participant set.

Implementations

impl Participant

pub const fn new(index: u32) -> Participant

Creates a new participant from a u32 index.

pub fn from_usize(index: usize) -> Participant

Creates a new participant from a usize index.

Panics

Panics if index exceeds u32::MAX.

pub const fn get(self) -> u32

Returns the underlying u32 index.

Trait Implementations

impl Clone for Participant

fn clone(&self) -> Participant

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Participant

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

Formats the value using the given formatter.

impl Default for Participant

fn default() -> Participant

Returns the “default value” for a type.

impl Display for Participant

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

Formats the value using the given formatter.

impl EncodeSize for Participant

fn encode_size(&self) -> usize

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

impl Hash for Participant

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 Participant

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

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

fn partial_cmp(&self, other: &Participant) -> 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 Participant

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: &<Participant as Read>::Cfg, ) -> Result<Participant, Error>

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

impl Write for Participant

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

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

impl Copy for Participant

impl Eq for Participant
