Type Alias NonAssocExpr 

pub type NonAssocExpr<Operand, Operator> = DelimitedVec<Operand, Operator, Forbidden, 1, 2>;

Type alias for non-associative binary operators.

Non-associative operators cannot be chained without parentheses. For example, comparison operators in Rust: a == b == c is a syntax error, must be (a == b) == c or a == (b == c).

This is a convenience alias for InfixExpr with default MAX=2, intended for documenting non-associative operators in expression grammars.

Examples

// Comparison operators are typically non-associative
type ComparisonExpr = NonAssocExpr<LiteralInteger, Equal>;

let mut tokens = "1 == 2".to_token_iter();
let expr: ComparisonExpr = tokens.parse().unwrap();
assert_eq!(expr.len(), 2);

Aliased Type

pub struct NonAssocExpr<Operand, Operator>(/* private fields */);
