Struct cairo_lang_lowering::objects::Variable

pub struct Variable {
    pub droppable: bool,
    pub duplicatable: bool,
    pub ref_indices: OrderedHashSet<usize>,
    pub ty: TypeId,
}

Lowered variable representation.

Fields

droppable: bool

Can the type be (trivially) dropped.

duplicatable: bool

Can the type be (trivially) duplicated.

ref_indices: OrderedHashSet<usize>

If this variable is a used as a reference variable (including implicits) of the current function, what are the indices of said reference variables? Note that a lowered variable might be assigned to multiple reference variables.

ty: TypeId

Semantic type of the variable.

Trait Implementations

impl Clone for Variable

fn clone(&self) -> Variable

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Variable

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

Formats the value using the given formatter.

impl PartialEq<Variable> for Variable

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