Struct PrefixExpression 

pub struct PrefixExpression {
    pub operator: PrefixOperator,
    pub expression: ArcIntern<Expression>,
}

The type of prefix Quil expressions, e.g. -e.

Quil expressions take advantage of structural sharing, which is why the expression here is wrapped in an ArcIntern; for more details, see the documentation for Expression.

Note that when comparing Quil expressions, any embedded NaNs are treated as equal to other NaNs, not unequal, in contravention of the IEEE 754 spec.

Fields

operator: PrefixOperator

expression: ArcIntern<Expression>

Implementations

impl PrefixExpression

pub fn new(operator: PrefixOperator, expression: ArcIntern<Expression>) -> Self

Trait Implementations

impl Clone for PrefixExpression

fn clone(&self) -> PrefixExpression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrefixExpression

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

Formats the value using the given formatter.

impl Hash for PrefixExpression

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for PrefixExpression

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