Enum Datum

pub enum Datum {
    IntegerDatum(BigInt),
    ByteStringDatum(Vec<u8>),
    ConstructorDatum {
        constructor: u64,
        fields: Vec<Datum>,
    },
    ListDatum(Vec<Datum>),
    MapDatum(Vec<MapDatumEntry>),
}

Plutus datum type

Variants

IntegerDatum(BigInt)

Integer value

ByteStringDatum(Vec<u8>)

Byte string value

ConstructorDatum

Constructor value

A Plutus constructor datum consists of an ordered list of Plutus field values together with numeric constructor ID that marks the constructor variant used. These can only be interpreted against an external schema that specifies expected content of fields and their interpretation.

Fields

constructor: u64

Constructor variant number

fields: Vec<Datum>

List of field values

ListDatum(Vec<Datum>)

List of values

MapDatum(Vec<MapDatumEntry>)

Key-value mapping

Implementations

impl Datum

pub fn as_bytestring(&self) -> Option<&Vec<u8>>

Returns byte content if self is a Datum::ByteStringDatum and None otherwise.

Trait Implementations

impl Clone for Datum

fn clone(&self) -> Datum

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Datum

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

Formats the value using the given formatter.

impl<C> Encode<C> for Datum

fn encode<W: Write>( &self, e: &mut Encoder<W>, ctx: &mut C, ) -> Result<(), Error<W::Error>>

Encode a value of this type using the given Encoder.

fn is_nil(&self) -> bool

Is this value of Self a nil value?

impl PartialEq for Datum

fn eq(&self, other: &Datum) -> 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 ToDatum for Datum

fn to_datum(&self) -> Datum

Encodes self to Datum.
