Enum Frame 

#[non_exhaustive]
pub enum Frame<'a> {
    Nodes {
        nodes: &'a [Node],
        index: usize,
        scoped: bool,
    },

Interpreter continuation stack.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Nodes

Sequence of nodes.

Fields

nodes: &'a [Node]

Nodes being executed.

index: usize

Next node index.

scoped: bool

Whether completion pops a lexical scope.

Loop

Bounded u32 loop.

Fields

var: &'a str

Loop variable name.

next: u32

Next induction value.

to: u32

Exclusive upper bound.

body: &'a [Node]

Loop body.
