Struct iota_types::digests::TransactionDigest

pub struct TransactionDigest(/* private fields */);

A transaction will have a (unique) digest.

Implementations

impl TransactionDigest

pub const ZERO: Self = _

pub const fn new(digest: [u8; 32]) -> Self

pub const fn genesis_marker() -> Self

A digest we use to signify the parent transaction was the genesis, ie. for an object there is no parent digest. Note that this is not the same as the digest of the genesis transaction, which cannot be known ahead of time.

pub fn generate<R: RngCore + CryptoRng>(rng: R) -> Self

pub fn random() -> Self

pub fn inner(&self) -> &[u8; 32]

pub fn into_inner(self) -> [u8; 32]

pub fn base58_encode(&self) -> String

pub fn next_lexicographical(&self) -> Option<Self>

Converts to this type from the input type.

impl FromStr for TransactionDigest

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for TransactionDigest

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 JsonSchema for TransactionDigest

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(gen: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl LowerHex for TransactionDigest

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

Formats the value using the given formatter.

impl Ord for TransactionDigest

fn cmp(&self, other: &TransactionDigest) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for TransactionDigest

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for TransactionDigest

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&[u8]> for TransactionDigest

type Error = IotaError
