Struct DataIdx 

pub struct DataIdx(u32);

Tuple Fields

0: u32

Implementations

impl DataIdx

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

Reads a data index from Wasm code without validating it.

Safety

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

impl DataIdx

pub fn validate(index: u32, data_count: u32) -> Result<Self, ValidationError>

Validates that a given index is a valid data index.

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

pub fn decode_and_validate( wasm: &mut WasmDecoder<'_>, data_count: u32, ) -> Result<Self, ValidationError>

Reads a data index from Wasm code and validates that it is a valid by comparing it to the total number of data segments.

Trait Implementations

impl Clone for DataIdx

fn clone(&self) -> DataIdx

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataIdx

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

Formats the value using the given formatter.

impl Display for DataIdx

impl Idx for DataIdx

fn new(index: u32) -> Self

fn into_inner(self) -> u32

impl Ord for DataIdx

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

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

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