Enum NodeOutput 

pub enum NodeOutput<'m> {
    NonTerminal,
    JetFailed,
    Success(FrameIter<'m>),
}

Write frame of a terminal (childless) Simplicity program node.

When a terminal node of a program is encountered in the Bit Machine, it has a well-defined “output”: the contents of the topmost write frame in the machine. In particular, for witness nodes this will be the witness data, for jets it will be the result of the jet, and so on.

For non-terminal nodes, the Bit Machine typically does some setup, then executes the nodes’ children, then does some teardown. So at no point is there a well-defined “output” we can provide.

Variants

NonTerminal

Non-terminal node, which has no output.

JetFailed

Node was a jet which failed, i.e. aborted the program, and therefore has no output.

Success(FrameIter<'m>)

Node succeeded. This is its output frame.
