Enum TotalControlFlow

pub enum TotalControlFlow {
    Halt,
    HaltIf,
    JumpForwardIf,
    PanicIf,
}

Control flow operations that keep the program total.

Variants

Halt

0x60: HLT

End the execution of the program.

HaltIf

0x61: HLTIF

Halt the program if the value is true.

Stack Input

[value]

JumpForwardIf

0x63: JMPIF

Jump forward the given number of instructions if the value is true.

Stack Input

[n_instruction, condition]

Panics

• The jump is negative.
• The jump distance is zero.

PanicIf

0x64: PNCIF

Panic if the condition is true.

Returns the stack at the time of the panic in the error message.

Stack Input

[condition]

Panics

• The condition is true.

Trait Implementations

impl Clone for TotalControlFlow

fn clone(&self) -> TotalControlFlow

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TotalControlFlow

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

Formats the value using the given formatter.

impl From<TotalControlFlow> for Constraint

fn from(subgroup: TotalControlFlow) -> Constraint

Converts to this type from the input type.

impl Hash for TotalControlFlow

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 Ord for TotalControlFlow

fn cmp(&self, other: &TotalControlFlow) -> 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,

Restrict a value to a certain interval.

impl PartialEq for TotalControlFlow

fn eq(&self, other: &TotalControlFlow) -> 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 PartialOrd for TotalControlFlow

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl ToBytes for TotalControlFlow

type Bytes = TotalControlFlow

The iterator yielding bytes.

fn to_bytes(&self) -> <TotalControlFlow as ToBytes>::Bytes

Convert the operation to its serialized form in bytes.

impl ToOpcode for TotalControlFlow

type Opcode = TotalControlFlow

The associated Opcode type.

fn to_opcode(&self) -> <TotalControlFlow as ToOpcode>::Opcode

The opcode associated with this operation.

impl TryFromBytes for TotalControlFlow

type Error = FromBytesError

Represents any error that might occur while parsing an op from bytes.

fn try_from_bytes( bytes: &mut impl Iterator<Item = u8>, ) -> Option<Result<TotalControlFlow, <TotalControlFlow as TryFromBytes>::Error>>

Parse a single operation from the given iterator yielding bytes.
