Struct Blake3Signer 

pub struct Blake3Signer { /* private fields */ }

BLAKE3 digest signer for high-throughput self-certifying content.

Uses signature type code SIGNATURE_TYPE_DIGEST_BLAKE3_PLAIN (6), reserved on the NDN TLV SignatureType registry. Analogous to DigestSha256 (type 0) but uses BLAKE3, which is 3–8× faster on modern CPUs due to SIMD parallelism.

The “signature” is a 32-byte BLAKE3 hash of the signed region. There is no secret key — this provides integrity (content addressing) but not authentication. For keyed BLAKE3 (authentication), use Blake3KeyedSigner, which uses a distinct type code so verifiers cannot be downgraded from keyed to plain mode via a substitution attack.

impl Blake3Signer

pub fn new(key_name: Name) -> Self

Trait Implementations

impl Signer for Blake3Signer

fn sig_type(&self) -> SignatureType

fn key_name(&self) -> &Name

fn sign<'a>( &'a self, region: &'a [u8], ) -> Pin<Box<dyn Future<Output = Result<Bytes, TrustError>> + Send + 'a>>

fn sign_sync(&self, region: &[u8]) -> Result<Bytes, TrustError>

Synchronous signing — avoids Box::pin and async state machine overhead.

fn cert_name(&self) -> Option<&Name>

The certificate name to embed as a key locator in SignatureInfo, if any.

fn public_key(&self) -> Option<Bytes>

Return the raw public key bytes, if available.
