}

Variants

Instruction(Instruction<N>)

Evaluates the instruction.

Await(Await<N>)

Awaits the result of a future.

Contains(Contains<N>)

Returns true if the key operand is present in mapping, and stores the result into destination.

Get(Get<N>)

Gets the value stored at the key operand in mapping and stores the result into destination.

GetOrUse(GetOrUse<N>)

Gets the value stored at the key operand in mapping and stores the result into destination. If the key is not present, default is stored destination.

RandChaCha(RandChaCha<N>)

Generates a random value using the rand.chacha command and stores the result into destination.

Remove(Remove<N>)

Removes the (key, value) entry from the mapping.

Set(Set<N>)

Sets the value stored at the key operand in the mapping to value.

BranchEq(BranchEq<N>)

Jumps to the position, if first equals second.

BranchNeq(BranchNeq<N>)

Jumps to the position, if first does not equal second.

Position(Position<N>)

Indicates a position to which the program can branch to.

Implementations

impl<N: Network> Command<N>

pub fn is_async(&self) -> bool

Returns true if the command is an async instruction.

pub fn is_await(&self) -> bool

Returns true if the command is an await command.

pub fn is_call(&self) -> bool

Returns true if the command is a call instruction.

pub fn is_cast_to_record(&self) -> bool

Returns true if the command is a cast to record instruction.

pub fn is_write(&self) -> bool

Returns true if the command is a write operation.

pub fn branch_to(&self) -> Option<&Identifier<N>>

Returns the branch target, if the command is a branch command. Otherwise, returns None.

pub fn position(&self) -> Option<&Identifier<N>>

Returns the position name, if the command is a position command. Otherwise, returns None.

pub fn destinations(&self) -> Vec<Register<N>>

Returns the destination registers of the command.

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

Returns the operands of the command.

pub fn finalize( &self, stack: &impl StackTrait<N>, store: &impl FinalizeStoreTrait<N>, registers: &mut impl FinalizeRegistersState<N>, ) -> Result<Option<FinalizeOperation<N>>>

Finalizes the command.

Trait Implementations

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

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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

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

Prints the command as a string.

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

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

Prints the command as a string.

impl<N: Network> FromBytes for Command<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.

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

where Self: Sized,

Same behavior as Self::from_bytes_le but avoids costly checks. This shall only be called when deserializing from a trusted source, such as local storage.

fn read_le_unchecked<R>(reader: R) -> Result<Self, Error>

where R: Read, Self: Sized,

Same behavior as Self::read_le but avoids costly checks. This shall only be called when deserializing from a trusted source, such as local storage.

fn read_le_with_unchecked<R>(reader: R, unchecked: bool) -> Result<Self, Error>

where R: Read, Self: Sized,

Helper function that deserializes either unchecked or checked based on the given boolean flag.

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

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

Parses the string into the command.

type Err = Error

The associated error which can be returned from parsing.

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

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

Parses the string into the command.

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

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

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

Writes the command 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.
