Struct Hole 

#[non_exhaustive]
pub struct Hole {
    pub source: String,
    pub plans: Vec<Plan>,
}

One $(…) inside a fragment: what it would run, as a plan.

A caller that decides the substitution is safe runs it in a kernel of its own construction — its own capabilities, its own timeout, its own cancellation — and expands again with the answer in the scope.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

source: String

The substitution rendered back to shell text, unexpanded: $(date +%s).

plans: Vec<Plan>

One plan per statement in the substitution’s body — the same vocabulary the enclosing statement’s plan uses, so a caller judging a hole reads it the way it reads everything else.
