pub struct LitExpr { /* fields omitted */ }

A literal expression.

Methods

impl LitExpr

pub fn new_integer(span: Span, value: BigInt) -> LitExpr

Create a new integer literal expression.

pub fn new_float(span: Span, value: BigRational) -> LitExpr

Create a new float literal expression.

pub fn value(&self) -> &LitExprValue

Return the constant value of the literal.

pub fn is_integer(&self) -> bool

Check if this is an integer literal.

pub fn is_float(&self) -> bool

Check if this is a floating-point literal.

pub fn integer_value(&self) -> Option<&BigInt>

Return the literal's integer value, or None if it is not an integer.

pub fn float_value(&self) -> Option<&BigRational>

Return the literal's float value, or None if it is not an float.
