Enum MemoryAddress

pub enum MemoryAddress {
    Direct(usize),
    Relative(usize),
}

Represents an address in the VM’s memory. Supports both direct and relative addressing.

Variants

Direct(usize)

Specifies an exact index in the VM’s memory.

Relative(usize)

Specifies an index relative to the stack pointer.

It is resolved as the current stack pointer plus the offset stored here.

The current stack pointer is wherever slot 0 of the Memory points at.

Implementations

impl MemoryAddress

pub fn direct(address: usize) -> Self

Create a Direct address.

pub fn relative(offset: usize) -> Self

Create a Relative address.

pub fn unwrap_direct(self) -> usize

Return the index in a Direct address.

Panics if it’s Relative.

pub fn unwrap_relative(self) -> usize

Return the index in a Relative address.

Panics if it’s Direct.

pub fn to_usize(self) -> usize

Return the index in the address.

pub fn is_relative(&self) -> bool

pub fn is_direct(&self) -> bool

pub fn offset(&self, amount: usize) -> Self

Offset the address by amount, while preserving its type.

Trait Implementations

impl Clone for MemoryAddress

fn clone(&self) -> MemoryAddress

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryAddress

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MemoryAddress

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for MemoryAddress

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

Formats the value using the given formatter.

impl Hash for MemoryAddress

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 Ord for MemoryAddress

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

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

fn partial_cmp(&self, other: &MemoryAddress) -> 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 Serialize for MemoryAddress

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
