Struct IifNode

#[non_exhaustive]
pub struct IifNode {
    pub test_expression: Box<Expression>,
    pub true_expression: Box<Expression>,
    pub false_expression: Box<Expression>,
    /* private fields */
}

A node representing the special IIF conditional syntax

E.g. IIF(A, B, C)

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

test_expression: Box<Expression>

The expression that represents the test or the conditional

true_expression: Box<Expression>

The expression to execute if the test returns true

false_expression: Box<Expression>

The expression to execute if the test returns false

Implementations

impl IifNode

pub fn new( test: impl Into<Box<Expression>>, t: impl Into<Box<Expression>>, f: impl Into<Box<Expression>>, ) -> Self

Create a new node

pub fn test(&self) -> &Expression

The expression that represents the test or the conditional

pub fn t(&self) -> &Expression

The expression to execute if the test returns true

pub fn f(&self) -> &Expression

The expression to execute if the test returns false

pub fn accept(&mut self, visitor: &mut impl Visitor)

Visit this node with the provided visitor

Trait Implementations

impl Clone for IifNode

fn clone(&self) -> IifNode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl From<IifNode> for Expression

fn from(node: IifNode) -> Expression

Converts to this type from the input type.

impl PartialEq for IifNode

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