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<'de> Deserialize<'de> for Advice

fn deserialize<__D>( __deserializer: __D, ) -> Result<Advice, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&ArchivedJournalAdviceV1> for Advice

fn from(val: &ArchivedJournalAdviceV1) -> Advice

Converts to this type from the input type.

impl From<Advice> for JournalAdviceV1

fn from(val: Advice) -> JournalAdviceV1

Converts to this type from the input type.

impl From<JournalAdviceV1> for Advice

fn from(val: JournalAdviceV1) -> Advice

Converts to this type from the input type.

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 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 Serialize for Advice

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

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 Copy for Advice

impl Eq for Advice

impl StructuralPartialEq for Advice
