Struct NestStep 

pub struct NestStep<'d> {
    pub var: Symbol<'d>,
    pub fixed: Option<(i32, i32)>,
    pub assoc: bool,
}

One enclosing foreach dimension on the way to a nested collection (RepeatCount::NestedSize): its index variable and, for a fixed-size dimension, its (left, right) bounds (None: a queue / dynamic array dimension, indexed from 0).

Fields

var: Symbol<'d>

fixed: Option<(i32, i32)>

assoc: bool

The dimension is an associative array: var holds a key, not a position.
