Prime header.

The length of the prime header is fixed, 8*32 = 256 bytes.

Implementations

impl PrimeHeader

pub fn prime_id(&self) -> PrimeId

Trait Implementations

impl Clone for PrimeHeader

fn clone(&self) -> PrimeHeader

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CommitEncode for PrimeHeader

type CommitmentId = PrimeId

Type of the resulting commitment.

fn commit_encode(&self, engine: &mut CommitEngine)

Encodes the data for the commitment by writing them directly into a std::io::Write writer instance

impl Debug for PrimeHeader

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PrimeHeader

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for PrimeHeader

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 Ord for PrimeHeader

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for PrimeHeader

fn eq(&self, other: &PrimeHeader) -> 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 PartialOrd for PrimeHeader

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl PublishedWitness<PrimeSeal> for PrimeHeader

type PubId = PrimeId

Publication id that may be used for referencing publication of witness data in the medium. By default, set (), so [SealProtocol] may not implement publication id and related functions.

type Error = InvalidProof

fn pub_id(&self) -> Self::PubId

fn verify_commitment(&self, msg: SealsHash) -> Result<(), Self::Error>

impl Serialize for PrimeHeader

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

fn strict_decode(reader: &mut impl TypedRead) -> Result<Self, DecodeError>

fn strict_read(reader: impl ReadRaw) -> Result<Self, DecodeError>

impl StrictDumb for PrimeHeader

fn strict_dumb() -> Self

impl StrictEncode for PrimeHeader

fn strict_encode<W: TypedWrite>(&self, writer: W) -> Result<W>
