Struct ThenElse 

pub struct ThenElse {
    pub condition: Box<Expr>,
    pub then_expr: Box<Expr>,
    pub else_expr: Box<Expr>,
    pub then_token: Token,
    pub else_token: Token,
}

Represents a then-else expression in the AST.

A then-else expression is used to conditionally evaluate one of two expressions.

Examples

let value = if condition then 42 else 0

Fields

condition: Box<Expr>

The condition expression.

then_expr: Box<Expr>

The expression to evaluate if the condition is true.

else_expr: Box<Expr>

The expression to evaluate if the condition is false.

then_token: Token

The token representing the then keyword.

else_token: Token

The token representing the else keyword.

Trait Implementations

impl Clone for ThenElse

fn clone(&self) -> ThenElse

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ThenElse

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

Formats the value using the given formatter.

impl GetSpan for ThenElse

fn span(&self) -> TextSpan

Returns the combined source span of the condition, then expression, and else expression.

impl PartialEq for ThenElse

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