EnterScope

ExitScope

AllocDictFeltTo

Fields

dict_manager_ptr: ResOperand

Allocates a new dict segment, and write its start address into the dict_infos segment.

DictFeltToRead

Fields

dict_ptr: ResOperand

key: ResOperand

value_dst: CellRef

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

DictFeltToWrite

Fields

dict_ptr: ResOperand

key: ResOperand

value: ResOperand

prev_value_dst: CellRef

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

GetDictIndex

Fields

dict_manager_ptr: ResOperand

dict_end_ptr: ResOperand

dict_index: CellRef

Retrives the index of the given dict in the dict_infos segment.

EnterDictSquashScope

Fields

dict_end_ptr: ResOperand

Creates a new scope with the variables needed for dict_squash.

SetDictTrackerEnd

Fields

squashed_dict_start: ResOperand

squashed_dict_end: ResOperand

Sets the end of a finalized dict in the vm tracker of the dict.

InitSquashData

Fields

dict_accesses: ResOperand

ptr_diff: ResOperand

n_accesses: ResOperand

big_keys: CellRef

first_key: CellRef

Initialized the lists of accesses of each key of a dict as a preparation of squash_dict.

GetCurrentAccessIndex

Fields

range_check_ptr: ResOperand

Retrives the current index of a dict access to process.

ShouldSkipSquashLoop

Fields

should_skip_loop: CellRef

Writes if the squash_dict loop should be skipped.

GetCurrentAccessDelta

Fields

index_delta_minus1: CellRef

Writes the delta from the current access index to the next one.

ShouldContinueSquashLoop

Fields

should_continue: CellRef

Writes if the squash_dict loop should be continued.

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.

GetNextDictKey

Fields

next_key: CellRef

Writes the next dict key to process.

AssertLtAssertValidInput

Fields

a: ResOperand

b: ResOperand

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

AssertLeFindSmallArcs

Fields

range_check_ptr: ResOperand

a: ResOperand

b: ResOperand

Finds the two small arcs from within [(0,a),(a,b),(b,PRIME)] and writes it to the range_check segment.

AssertLeIsFirstArcExcluded

Fields

skip_exclude_a_flag: CellRef

Writes if the arc (0,a) was excluded.

AssertLeIsSecondArcExcluded

Fields

skip_exclude_b_minus_a: CellRef

Writes if the arc (a,b) was excluded.

AssertLeAssertThirdArcExcluded

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

RandomEcPoint

Fields

x: CellRef

y: CellRef

Samples a random point on the EC.

FieldSqrt

Fields

val: ResOperand

sqrt: CellRef

Computes the square root of val, if val is a quadratic residue, and of 3 * val otherwise.

Since 3 is not a quadratic residue, exactly one of val and 3 * val is a quadratic residue (unless val is 0). This allows proving that val is not a quadratic residue.

SystemCall

Fields

system: ResOperand

Represents a hint that triggers a system call.

DebugPrint

Fields

start: ResOperand

end: ResOperand

Prints the values from start to end. Both must be pointers.

AllocConstantSize

Fields

size: ResOperand

dst: CellRef

Returns an address with size free locations afterwards.

Trait Implementations

impl Clone for Hint

fn clone(&self) -> Hint

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Hint

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

Formats the value using the given formatter.

impl Display for Hint

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

Formats the value using the given formatter.

impl PartialEq<Hint> for Hint

fn eq(&self, other: &Hint) -> 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.
