Struct muse_lang::compiler::syntax::IfExpression

pub struct IfExpression {
    pub if: Ranged<Token>,
    pub condition: Ranged<Expression>,
    pub then: Option<Ranged<Token>>,
    pub when_true: Ranged<Expression>,
    pub when_false: Option<Else>,
}

The syntax components of an if expression.

Fields

if: Ranged<Token>

The if keyword.

condition: Ranged<Expression>

The condition being checked.

then: Option<Ranged<Token>>

If a then keyword is provided instead of when_true being a block, this contains it.

when_true: Ranged<Expression>

The expression to evaluate if condition is truthy.

when_false: Option<Else>

The expression to evaluate if condition is falsey.

Trait Implementations

impl Clone for IfExpression

fn clone(&self) -> IfExpression

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IfExpression

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

Formats the value using the given formatter.

impl PartialEq for IfExpression

fn eq(&self, other: &IfExpression) -> 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 TokenizeInto for IfExpression

fn tokenize_into(&self, tokens: &mut VecDeque<Ranged<Token>>)

Tokenize self into tokens.

fn to_tokens(&self) -> VecDeque<Ranged<Token>>

Returns a list of tokens that could be re-parsed to produce this value.
