Struct Signers 

pub struct Signers { /* private fields */ }

Bitmap wrapper that tracks which participants signed a certificate.

Internally, it stores bits in 1-byte chunks for compact encoding.

Implementations

impl Signers

pub fn from( participants: usize, signers: impl IntoIterator<Item = Participant>, ) -> Self

Builds Signers from an iterator of signer indices.

Panics

Panics if the sequence contains indices larger than the size of the participant set or duplicates.

pub const fn len(&self) -> usize

Returns the length of the bitmap (the size of the participant set).

pub fn count(&self) -> usize

Returns how many participants are marked as signers.

pub fn iter(&self) -> impl Iterator<Item = Participant> + '_

Iterates over signer indices in ascending order.

Trait Implementations

impl Clone for Signers

fn clone(&self) -> Signers

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Signers

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

Formats the value using the given formatter.

impl EncodeSize for Signers

fn encode_size(&self) -> usize

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

impl Hash for Signers

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 PartialEq for Signers

fn eq(&self, other: &Signers) -> 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 Read for Signers

type Cfg = usize

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( reader: &mut impl Buf, max_participants: &usize, ) -> Result<Self, Error>

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

impl Write for Signers

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

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