Struct MemoryIndex

pub struct MemoryIndex(/* private fields */);

Index type of a linear memory (imported or local) inside the WebAssembly module.

Implementations

impl MemoryIndex

pub fn from_u32(x: u32) -> Self

Create a new instance from a u32.

pub fn as_u32(self) -> u32

Return the underlying index value as a u32.

Trait Implementations

impl Archive for MemoryIndex

where u32: Archive,

type Archived = MemoryIndex

The archived representation of this type.

type Resolver = MemoryIndexResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

unsafe fn resolve( &self, pos: usize, resolver: Self::Resolver, out: *mut Self::Archived, )

Creates the archived version of this value at the given position and writes it to the given output.

impl<__C: ?Sized> CheckBytes<__C> for MemoryIndex

where u32: CheckBytes<__C>,

type Error = TupleStructCheckError

The error that may result from checking the type.

unsafe fn check_bytes<'__bytecheck>( value: *const Self, context: &mut __C, ) -> Result<&'__bytecheck Self, TupleStructCheckError>

Checks whether the given pointer points to a valid value within the given context.

impl Clone for MemoryIndex

fn clone(&self) -> MemoryIndex

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryIndex

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

Formats the value using the given formatter.

impl<__D: Fallible + ?Sized> Deserialize<MemoryIndex, __D> for Archived<MemoryIndex>

where u32: Archive, Archived<u32>: Deserialize<u32, __D>,

fn deserialize(&self, deserializer: &mut __D) -> Result<MemoryIndex, __D::Error>

Deserializes using the given deserializer

impl EntityRef for MemoryIndex

fn new(index: usize) -> Self

Create a new entity reference from a small integer. This should crash if the requested index is not representable.

fn index(self) -> usize

Get the index that was used to create this entity reference.

impl Hash for MemoryIndex

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 MemoryIndex

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

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

fn partial_cmp(&self, other: &MemoryIndex) -> 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 ReservedValue for MemoryIndex

fn reserved_value() -> MemoryIndex

Create an instance of the reserved value.

fn is_reserved_value(&self) -> bool

Checks whether value is the reserved one.

impl<__S: Fallible + ?Sized> Serialize<__S> for MemoryIndex

where u32: Serialize<__S>,

fn serialize(&self, serializer: &mut __S) -> Result<Self::Resolver, __S::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.
