Struct SignatureBlock 

pub struct SignatureBlock {
    pub signature: [u8; 64],
    pub public_key: [u8; 32],
}

Dataset signature block

Fields

signature: [u8; 64]

The Ed25519 signature (64 bytes)

public_key: [u8; 32]

The signer’s public key (32 bytes)

Implementations

impl SignatureBlock

pub const SIZE: usize

Size of the signature block in bytes (64 + 32 = 96)

pub fn sign(data: &[u8], key_pair: &SigningKeyPair) -> Self

Create a new signature block by signing data

pub fn verify(&self, data: &[u8]) -> Result<()>

Verify the signature against the given data

Errors

Returns error if signature verification fails.

pub fn to_bytes(&self) -> [u8; 96]

Serialize to bytes (96 bytes: signature + public_key)

pub fn from_bytes(buf: &[u8]) -> Result<Self>

Deserialize from bytes

Errors

Returns error if buffer is too small.

Trait Implementations

fn clone(&self) -> SignatureBlock

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SignatureBlock

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