Variants

AllocSlots

0x80

Allocate new slots to the end of the memory.

Stack Input

[size]

Load

0x81

Load the value at the index of a slot onto the stack.

Noop if the slot is empty.

Stack Input

[index]

Stack Output

[value_word, ...] The stack output length depends on the value of the value_len stack input word.

Panics

• Index is out of bounds.

Store

0x82

Store the value at the index of state slots.

Stack Input

[value_word_0, ...value_word_len, len, index]

Panics

• Index is out of bounds.

LoadWord

0x83

Load the word at the index of the value at the slot onto the stack.

Stack Input

[slot, index]

Stack Output

[Value_word]

Panics

• Slot or Index is out of bounds.

StoreWord

0x84

Store the word at the index of the value at the slot.

Stack Input

[slot, index, word]

Panics

• Slot or Index is out of bounds.

Clear

0x85

Clear the value at the index.

Stack Input

[index]

Panics

• Index is out of bounds.

ClearRange

0x86

Clear a range of values.

Stack Input

[index, amount]

Panics

• The range is out of bounds.

Length

0x87

Get the current length of the memory.

Stack Output

[length]

ValueLen

0x88

Get the current length of a given value at the index.

Stack Input

[index]

Stack Output

[length]

Trait Implementations

impl Clone for StateSlots

fn clone(&self) -> StateSlots

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StateSlots

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

Formats the value using the given formatter.

impl From<StateSlots> for StateRead

fn from(subgroup: StateSlots) -> StateRead

Converts to this type from the input type.

impl Hash for StateSlots

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 StateSlots

fn cmp(&self, other: &StateSlots) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for StateSlots

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

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl ToBytes for StateSlots

type Bytes = StateSlots

The iterator yielding bytes.

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

Convert the operation to its serialized form in bytes.

impl ToOpcode for StateSlots

type Opcode = StateSlots

The associated Opcode type.

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

The opcode associated with this operation.

impl TryFromBytes for StateSlots

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<StateSlots, <StateSlots as TryFromBytes>::Error>>

Parse a single operation from the given iterator yielding bytes.

impl Copy for StateSlots

impl Eq for StateSlots

impl StructuralPartialEq for StateSlots
