Struct StateData

pub struct StateData {
    pub value: StateValue,
    pub raw: Option<RawData>,
}

State kept in the immutable (read-only) memory cells.

Fields

value: StateValue

The verifiable and compressible part of the state, in the form of field elements.

raw: Option<RawData>

Optional raw state, which cannot be accessed by the verification scripts and zk-AluVM, and are not compressible as a part of zk proofs.

Implementations

impl StateData

pub fn new(ty: impl Into<fe256>, val: impl Into<fe256>) -> StateData

Constructs a new state value in StateValue::Double form, using the first element to store the value “type” from the first argument, and the second argument to store the data, which can be anything representable with a single 256-bit field element.

Leaves raw data empty.

pub fn with_raw( ty: impl Into<fe256>, val: impl Into<fe256>, raw: impl Into<RawData>, ) -> StateData

Constructs a new state value in StateValue::Double form, using the first element to store the value “type” from the first argument, and the second argument to store the data, which can be anything representable with a single 256-bit field element.

Adds to that value raw data.

Trait Implementations

impl Clone for StateData

fn clone(&self) -> StateData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CommitEncode for StateData

type CommitmentId = MerkleHash

Type of the resulting commitment.

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

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

impl Debug for StateData

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StateData

fn deserialize<__D>( __deserializer: __D, ) -> Result<StateData, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for StateData

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 StateData

fn eq(&self, other: &StateData) -> 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 StateData

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StrictDecode for StateData

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

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

impl StrictDumb for StateData

fn strict_dumb() -> StateData

impl StrictEncode for StateData

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

where W: TypedWrite,

fn strict_write(&self, writer: impl WriteRaw) -> Result<(), Error>

impl StrictStruct for StateData

const ALL_FIELDS: &'static [&'static str]

fn strict_check_fields()

fn strict_type_info() -> TypeInfo<Self>

impl StrictType for StateData

const STRICT_LIB_NAME: &'static str = LIB_NAME_ULTRASONIC

fn strict_name() -> Option<TypeName>
