Function clippy_utils::if_sequence

pub fn if_sequence<'tcx>(
    expr: &'tcx Expr<'tcx>
) -> (Vec<&'tcx Expr<'tcx>>, Vec<&'tcx Block<'tcx>>)

Returns the list of condition expressions and the list of blocks in a sequence of if/else. E.g., this returns ([a, b], [c, d, e]) for the expression if a { c } else if b { d } else { e }.
