Struct snarkvm_synthesizer_program::logic::command::RandChaCha

pub struct RandChaCha<N: Network> { /* private fields */ }

A random-number generator command, e.g. rand.chacha into r1 as field; or rand.chacha r0 into r1 as field;, with the latter including an optional additional seed(s).

This command samples a deterministic and unique element, and stores the result in destination. When the optional operand(s) are provided, it is used as additional seed(s) to the random-number generator. Note that the maximum number of additional seeds is currently 2.

Implementations

impl<N: Network> RandChaCha<N>

pub const fn opcode() -> Opcode

Returns the opcode.

pub fn operands(&self) -> Vec<Operand<N>>

Returns the operands in the operation.

pub const fn destination(&self) -> &Register<N>

Returns the destination register.

pub const fn destination_type(&self) -> LiteralType

Returns the destination register type.

impl<N: Network> RandChaCha<N>

pub fn finalize( &self, stack: &(impl StackMatches<N> + StackProgram<N>), registers: &mut (impl RegistersLoad<N> + RegistersStore<N> + FinalizeRegistersState<N>) ) -> Result<()>

Finalizes the command.

Trait Implementations

impl<N: Clone + Network> Clone for RandChaCha<N>

fn clone(&self) -> RandChaCha<N>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<N: Network> Debug for RandChaCha<N>

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

Prints the command as a string.

impl<N: Network> Display for RandChaCha<N>

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

Prints the command to a string.

impl<N: Network> FromBytes for RandChaCha<N>

fn read_le<R: Read>(reader: R) -> IoResult<Self>

Reads the command from a buffer.

fn from_bytes_le(bytes: &[u8]) -> Result<Self, Error>where Self: Sized,

Returns Self from a byte array in little-endian order.

impl<N: Network> FromStr for RandChaCha<N>

fn from_str(string: &str) -> Result<Self>

Parses a string into the command.

type Err = Error

The associated error which can be returned from parsing.

impl<N: Hash + Network> Hash for RandChaCha<N>

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<N: Network> Parser for RandChaCha<N>

fn parse(string: &str) -> ParserResult<'_, Self>

Parses a string into an operation.

impl<N: PartialEq + Network> PartialEq for RandChaCha<N>

fn eq(&self, other: &RandChaCha<N>) -> 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<N: Network> ToBytes for RandChaCha<N>

fn write_le<W: Write>(&self, writer: W) -> IoResult<()>

Writes the operation to a buffer.

fn to_bytes_le(&self) -> Result<Vec<u8>, Error>where Self: Sized,

Returns self as a byte array in little-endian order.
