Struct Siger 

pub struct Siger<'a> { /* private fields */ }

Available on crate feature core only.

An indexed signature primitive.

Wraps an Indexer (which holds the code, index, ondex, and raw signature bytes) and optionally carries the Verfer (verification key) associated with the signer index.

Construct a Siger by first building an Indexer via IndexerBuilder, then passing it to Siger::new.

Implementations

impl<'a> Siger<'a>

pub const fn new(indexer: Indexer<'a>) -> Self

Creates a new Siger from an Indexer, with no attached verfer.

pub fn with_verfer(self, verfer: Verfer<'a>) -> Self

Builder method: attaches a Verfer (verification key) to this siger.

pub const fn code(&self) -> IndexedSigCode

Returns the CESR indexed signature code.

pub const fn index(&self) -> u32

Returns the signer’s index in the key list.

pub const fn ondex(&self) -> Option<u32>

Returns the “other index” (prior-next key list index), if present.

pub fn raw(&self) -> &[u8]

Returns the raw signature bytes.

pub const fn verfer(&self) -> Option<&Verfer<'a>>

Returns a reference to the attached verfer, if any.

pub fn full_size(&self) -> usize

Returns the full CESR-encoded size in characters.

pub fn to_qb64(&self) -> String

Encodes this indexed signature into its qualified Base64 (qb64) CESR wire format.

pub fn to_qb2(&self) -> Vec<u8>

Encodes this indexed signature into its qualified binary (qb2) CESR wire format.

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

Performs copy-assignment from source.

impl Debug for Siger<'_>

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

Formats the value using the given formatter.

impl Eq for Siger<'_>

impl PartialEq for Siger<'_>

fn eq(&self, other: &Self) -> bool
