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 new( participants: u32, signers: impl IntoIterator<Item = Participant>, ) -> Result<Self, AssemblyError>

Builds Signers from an iterator of signer indices.

Indices need not be sorted: some signing schemes aggregate commutatively, so ordering is left to the caller.

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) -> Self

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).

fn encode_inline_size(&self) -> usize

Returns the encoded size excluding bytes passed to BufsMut::push during Write::write_bufs. Used to size the fixed working buffer for inline writes, so it must not be less than the bytes written inline. Override alongside Write::write_bufs for types where large byte fields go via push, or the working buffer will over-allocate.

impl Eq for Signers

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: &Self) -> bool

Equality operator ==.

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

Inequality operator !=.

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, CodecError>

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

impl StructuralPartialEq for Signers

impl<'a, P, I> TryFrom<(&'a Set<P>, I)> for Signers

where I: IntoIterator<Item = Participant>,

Builds Signers using the participant set as the valid signer-index range.

Panics

Panics if the participant count exceeds u32::MAX.

type Error = AssemblyError

The type returned in the event of a conversion error.

fn try_from( (participants, signers): (&'a Set<P>, I), ) -> Result<Self, Self::Error>

Performs the conversion.

impl<'a, V, I> TryFrom<(&'a Sharing<V>, I)> for Signers

where V: Variant, I: IntoIterator<Item = Participant>,

Builds Signers using the sharing’s participant bound and recovery threshold.

type Error = AssemblyError

The type returned in the event of a conversion error.

fn try_from((quorum, signers): (&'a Sharing<V>, I)) -> Result<Self, Self::Error>

Performs the conversion.

impl Write for Signers

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

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

fn write_bufs(&self, buf: &mut impl BufsMut)

Writes to a BufsMut, allowing existing byte chunks to be appended via BufsMut::push instead of written inline. Must encode to the same format as Write::write. Defaults to Write::write.
