Holds static information about extern functions required for const calculations.

Fields

upcast_fns: UnorderedHashSet<ExternFunctionId<'db>>

The integer upcast style functions.

downcast_fns: UnorderedHashMap<ExternFunctionId<'db>, bool>

The integer downcast style functions, mapping to whether it returns a reversed Option enum.

u128s_from_felt252: ExternFunctionId<'db>

The felt252 into u128 words libfunc.

nz_fns: UnorderedHashSet<ExternFunctionId<'db>>

The is_zero style functions.

type_value_ranges: UnorderedHashMap<TypeId<'db>, TypeRange>

The range of values of a numeric type.

Trait Implementations

impl<'db> Debug for ConstCalcInfo<'db>

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

Formats the value using the given formatter.

impl<'db> Deref for ConstCalcInfo<'db>

type Target = CoreInfo<'db>

The resulting type after dereferencing.

fn deref(&self) -> &CoreInfo<'db>

Dereferences the value.

impl<'db> PartialEq for ConstCalcInfo<'db>

fn eq(&self, other: &ConstCalcInfo<'db>) -> 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<'db> Update for ConstCalcInfo<'db>

unsafe fn maybe_update(old_pointer_: *mut Self, new_value_: Self) -> bool

Returns

impl<'db> Eq for ConstCalcInfo<'db>

impl<'db> StructuralPartialEq for ConstCalcInfo<'db>
