Struct Conditional

pub struct Conditional {
    pub cond_expr: Expression,
    pub true_expr: Expression,
    pub false_expr: Expression,
    /* private fields */
}

The conditional operator allows selecting from one of two expressions based on the outcome of a boolean expression.

Fields

cond_expr: Expression

A condition expression that evaluates to a boolean value.

true_expr: Expression

The expression returned by the conditional if the condition evaluates to true.

false_expr: Expression

The expression returned by the conditional if the condition evaluates to false.

Implementations

impl Conditional

pub fn new( cond_expr: impl Into<Expression>, true_expr: impl Into<Expression>, false_expr: impl Into<Expression>, ) -> Conditional

Creates a new Conditional from a condition and two expressions for the branches of the conditional.

Trait Implementations

impl Clone for Conditional

fn clone(&self) -> Conditional

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Conditional

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

Formats the value using the given formatter.

impl Decorate for Conditional

fn decor(&self) -> &Decor

Returns a reference to the object’s Decor.

fn decor_mut(&mut self) -> &mut Decor

Returns a mutable reference to the object’s Decor.

fn decorate(&mut self, decor: impl Into<Decor>)

Decorate the object with decor in-place.

fn decorated(self, decor: impl Into<Decor>) -> Self

where Self: Sized,

Decorate the object with decor and return the modified value.

impl From<Conditional> for Expression

fn from(value: Conditional) -> Self

Converts to this type from the input type.

impl PartialEq for Conditional

fn eq(&self, other: &Self) -> 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 Span for Conditional

fn span(&self) -> Option<Range<usize>>

Obtains the span information. This only returns Some if the value was emitted by the parser.

impl Eq for Conditional
