Struct rune::ast::LitTuple

pub struct LitTuple {
    pub open: OpenParen,
    pub items: Vec<(Expr, Option<Comma>)>,
    pub close: CloseParen,
    // some fields omitted
}

An expression to construct a literal tuple.

Fields

open: OpenParen

items: Vec<(Expr, Option<Comma>)>

Items in the tuple.

close: CloseParen

The close bracket.

pub fn parse_from_first_expr(
    parser: &mut Parser<'_>,
    open: OpenParen,
    expr: Expr
) -> Result<Self, ParseError>

Start parsing literal tuple from the middle of an expression.
