Implementations

impl Artifact

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

Parse artifact from bytes (auto-detects v1 vs v2)

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

Get bytes that were signed by author

pub fn seal_signing_bytes(&self) -> Result<Vec<u8>>

Get bytes that were signed by seal (V2 only). Returns Err if the artifact has no seal (seal_pubkey is all zeros).

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

Serialize artifact to bytes

pub fn write_to<W: Write>(&self, writer: &mut W) -> Result<()>

Write artifact to a writer

pub fn read_from<R: Read>(reader: &mut R) -> Result<Self>

Read artifact from a reader

pub fn author_fingerprint(&self) -> KeyFingerprint

Get author key fingerprint

pub fn seal_fingerprint(&self) -> Option<KeyFingerprint>

Get seal key fingerprint (V2 only)

pub fn is_sealed(&self) -> bool

Check if artifact is sealed

pub fn has_author_signature(&self) -> bool

Check if artifact has author signature

pub fn has_signature(&self) -> bool

Check if artifact has a signature (legacy compatibility)

pub fn has_author_pubkey(&self) -> bool

Check if artifact has an author public key (keyless draft = all zeros)

pub fn has_note_hash(&self) -> bool

Check if note hash is present (V2 only)

pub fn state(&self) -> ArtifactState

Determine artifact state

pub fn with_seal_flag(self) -> Self

Set seal flag (V1 only - returns new artifact with flag set)

pub fn without_seal_flag(self) -> Self

Clear seal flag (V1 only - returns new artifact with flag cleared)

pub fn without_author_signature(self) -> Self

Remove author signature

pub fn without_signature(self) -> Self

Remove signature (legacy compatibility)

pub fn without_seal_signature(self) -> Self

Remove seal signature (V2 only)

pub fn with_seal(self, seal_pubkey: [u8; 32], seal_signature: [u8; 64]) -> Self

Add seal signature (V2 only)

Trait Implementations

impl Clone for Artifact

fn clone(&self) -> Artifact

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Artifact

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

Formats the value using the given formatter.
