Struct SealRef 

pub struct SealRef {
    pub seal_id: Vec<u8>,
    pub nonce: Option<u64>,
}

A reference to a single-use seal

The concrete meaning is chain-specific:

• Bitcoin: UTXO OutPoint
• Ethereum: Contract address + storage slot
• Sui: Object ID
• Aptos: Resource address + key

Fields

seal_id: Vec<u8>

Chain-specific seal identifier

nonce: Option<u64>

Optional nonce for replay resistance

Implementations

impl SealRef

pub fn new(seal_id: Vec<u8>, nonce: Option<u64>) -> Result<Self, &'static str>

Create a new SealRef from raw bytes

Arguments

• seal_id - Chain-specific seal identifier (max 1KB)
• nonce - Optional nonce for replay resistance

Errors

Returns an error if the seal_id exceeds the maximum allowed size

pub fn new_unchecked(seal_id: Vec<u8>, nonce: Option<u64>) -> Self

Create a new SealRef without validation.

Safety

This bypasses size validation. Use only for internal protocol conversions where the input is already known to be valid.

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

Serialize to bytes

Format: [nonce_flag(1) | nonce_bytes(8 if flag=1) | seal_id_len(varuint) | seal_id] The nonce_flag is 1 for Some(nonce), 0 for None.

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

Deserialize from bytes

Errors

Returns an error if the bytes are malformed or seal_id exceeds the maximum allowed size.

Trait Implementations

impl Clone for SealRef

fn clone(&self) -> SealRef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SealRef

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SealRef

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for SealRef

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 SealRef

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for SealRef

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
