Sequential

Random

The application expects to access the specified data in a random order.

Dontneed

Noreuse

Trait Implementations

impl Clone for Advice

fn clone(&self) -> Advice

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Advice

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

Formats the value using the given formatter.

impl FromToNativeWasmType for Advice

type Native = i32

Native Wasm type.

fn to_native(self) -> <Advice as FromToNativeWasmType>::Native

Convert self to Self::Native.

fn from_native(n: <Advice as FromToNativeWasmType>::Native) -> Advice

Convert a value of kind Self::Native to Self.

fn is_from_store(&self, _store: &impl AsStoreRef) -> bool

Returns whether the given value is from the given store.

impl PartialEq<Advice> for Advice

fn eq(&self, other: &Advice) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ValueType for Advice

fn zero_padding_bytes(&self, _bytes: &mut [MaybeUninit<u8>])

This method is passed a byte slice which contains the byte representation of self. It must zero out any bytes which are uninitialized (e.g. padding bytes).

impl StructuralEq for Advice
