Enum StateMemory

pub enum StateMemory {
    AllocSlots,
    Load,
    Store,
    Truncate,
    Length,
    ValueLen,
}

Operations for controlling mutable state slots.

Variants

AllocSlots

0x80: ALOCS

Allocate new slots to the end of the memory.

Stack Input

[size]

Load

0x81: LODSM

Access a range of len words starting from value_ix within the memory slot located at slot_ix.

Returns a list of words with length equal to the specified len.

Stack Input

[slot_ix, value_ix, len]

Stack Output

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

Panics

• slot_ix is out of bounds.
• The range value_ix..(value_ix + len) is out of range.

Store

0x82: STOSM

Store len words of data at the slot_ix starting at value_ix.

Stack Input

[slot_ix, value_ix, data, len]

Panics

• slot_ix is out of bounds.
• value_ix > ValueLen.
• len is out of bounds.

Truncate

0x83: TRUNC

Truncate the memory slot located at slot_ix to len words.

Stack Input

[slot_ix, len]

Panics

• slot_ix is out of bounds.

Length

0x84: SMLEN

Get the current length of the memory.

Stack Output

[length]

ValueLen

0x85: SMVLEN

Get the current length of the value at the slot_ix.

Stack Input

[slot_ix]

Stack Output

[length]

Trait Implementations

impl Clone for StateMemory

fn clone(&self) -> StateMemory

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StateMemory

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

Formats the value using the given formatter.

impl From<StateMemory> for StateRead

fn from(subgroup: StateMemory) -> StateRead

Converts to this type from the input type.

impl Hash for StateMemory

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 StateMemory

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

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

fn partial_cmp(&self, other: &StateMemory) -> 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 StateMemory

type Bytes = StateMemory

The iterator yielding bytes.

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

Convert the operation to its serialized form in bytes.

impl ToOpcode for StateMemory

type Opcode = StateMemory

The associated Opcode type.

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

The opcode associated with this operation.

impl TryFromBytes for StateMemory

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<StateMemory, <StateMemory as TryFromBytes>::Error>>

Parse a single operation from the given iterator yielding bytes.

impl Copy for StateMemory

impl Eq for StateMemory
