Struct MemIdx 

pub struct MemIdx(u32);

Tuple Fields

0: u32

Implementations

impl MemIdx

pub unsafe fn decode_unchecked(wasm: &mut WasmDecoder<'_>) -> Self

Reads a memory index from Wasm code without validating it.

Safety

The caller must ensure that there is a valid memory index in the WasmDecoder.

impl MemIdx

pub fn validate<T>( index: u32, c_mems: &IdxVec<MemIdx, T>, ) -> Result<Self, ValidationError>

Validates that a given index is a valid memory index.

On success a new MemIdx is returned, otherwise a ValidationError is returned.

pub fn decode_and_validate<T>( wasm: &mut WasmDecoder<'_>, c_mems: &IdxVec<MemIdx, T>, ) -> Result<Self, ValidationError>

Reads a memory index from Wasm code and validates that it is a valid index for a given memories vector.

Trait Implementations

impl Clone for MemIdx

fn clone(&self) -> MemIdx

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MemIdx

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

Formats the value using the given formatter.

impl Display for MemIdx

impl Idx for MemIdx

fn new(index: u32) -> Self

fn into_inner(self) -> u32

impl Ord for MemIdx

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

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

fn partial_cmp(&self, other: &MemIdx) -> 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.
