Represents a deprecated hint which is kept for backward compatibility of previously deployed contracts.

Variants

AssertCurrentAccessIndicesIsEmpty

Asserts that the current access indices list is empty (after the loop).

AssertAllAccessesUsed

Fields

n_used_accesses: CellRef

Asserts that the number of used accesses is equal to the length of the original accesses list.

AssertAllKeysUsed

Asserts that the keys list is empty.

AssertLeAssertThirdArcExcluded

Asserts that the arc (b, PRIME) was excluded.

AssertLtAssertValidInput

Fields

a: ResOperand

b: ResOperand

Asserts that the input represents integers and that a<b.

Felt252DictRead

Fields

dict_ptr: ResOperand

key: ResOperand

value_dst: CellRef

Retrieves and writes the value corresponding to the given dict and key from the vm dict_manager.

Felt252DictWrite

Fields

dict_ptr: ResOperand

key: ResOperand

value: ResOperand

Sets the value corresponding to the key in the vm dict_manager.

Trait Implementations

impl Clone for DeprecatedHint

fn clone(&self) -> DeprecatedHint

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DeprecatedHint

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

Formats the value using the given formatter.

impl Decode for DeprecatedHint

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy ) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self> ) -> Result<DecodeFinished, Error>where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl<'de> Deserialize<'de> for DeprecatedHint

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

Deserialize this value from the given Serde deserializer.

impl Encode for DeprecatedHint

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy )

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> Rwhere F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl From<DeprecatedHint> for CoreHintBase

fn from(value: DeprecatedHint) -> Self

Converts to this type from the input type.

impl JsonSchema for DeprecatedHint

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(gen: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl PartialEq for DeprecatedHint

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

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

Serialize this value into the given Serde serializer.
