Enum Memory

pub enum Memory {
    Alloc,
    Free,
    Load,
    Store,
    LoadRange,

}

Operations for memory.

Variants

Alloc

0x70: ALOC

Allocate a new block of memory to the end.

Sets new memory to 0.

Returns the index to the start of the new block of memory.

Allocate 0 to get the current length of the memory.

Stack Input

[size]

Stack Output

[index]

Panics

• Max memory size reached.

Free

0x71

Truncate memory to the specified new length, freeing all that follows.

Stack Input

[new_length]

Panics

• The new length is negative.
• The new length is greater than the existing length.

Load

0x72: LOD

Load the value at the given index from memory onto the stack.

Stack Input

[index]

Stack Output

[value]

Panics

• Index is out of bounds.

Store

0x73: STO

Store the value at the given index within memory.

Stack Input

[value, index]

Panics

• Index is out of bounds.

LoadRange

0x74: LODR

Load a range of words starting at the index within memory.

Stack Input

[index, len]

Stack Output

[values]

Panics

• Index is out of bounds.
• Index + len is out of bounds.

StoreRange

0x75: STOR

Store a range of words starting at the index within memory.

Stack Input

[values, len, index]

Panics

• Index is out of bounds.
• Index + len is out of bounds.

Trait Implementations

impl Clone for Memory

fn clone(&self) -> Memory

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Memory

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

Formats the value using the given formatter.

impl From<Memory> for Op

fn from(subgroup: Memory) -> Op

Converts to this type from the input type.

impl Hash for Memory

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 Memory

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

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

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

type Bytes = Memory

The iterator yielding bytes.

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

Convert the operation to its serialized form in bytes.

impl ToOpcode for Memory

type Opcode = Memory

The associated Opcode type.

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

The opcode associated with this operation.

impl TryFromBytes for Memory

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<Memory, <Memory as TryFromBytes>::Error>>

Parse a single operation from the given iterator yielding bytes.

impl Copy for Memory

impl Eq for Memory
