Compiled functions by source (spec/08 §10.5.3, D-194): a value, held by whatever owns the functions — a board's engine, the builder — not a process or a table, as the schema cache is (spec/08 §10.3).
An entry is keyed by the SHA-256 of the source, the arities, the fields and the variables
it was checked against (D-228), and holds the compilation's answer, a refusal included,
so a source is checked and compiled once. A compilation the runner cut short
(:reductions, :hung, :memory) is not kept, since it says nothing about the source.
The cache never evicts.
Summary
Functions
compile(cache, source, opts): {:ok, compiled, cache} or {:error, faults, cache},
as Visualize.VirtualSource.Sandbox.compile/2 answers, compiled at most once per
source, arities, fields and variables.
The empty cache.
