# `Riddler.Template.Compiled`
[🔗](https://github.com/riddler/riddler-ex/blob/v0.4.0/lib/riddler/template/compiled.ex#L1)

A template that has been accepted by `Riddler.Template.compile/1`.

Holding one of these is the proof that every construct in the source is
inside the template subset: nothing outside it survives compilation, so a
render can never be the first place a refusal is discovered.

The struct is opaque in practice - a host keeps it and hands it back to
`Riddler.Template.render/3` - but its fields are readable so that a host
that caches compiled templates can key them on the source it compiled.

# `t`

```elixir
@type t() :: %Riddler.Template.Compiled{
  defaulted: MapSet.t({pos_integer(), pos_integer()}),
  parsed: Solid.Template.t(),
  source: String.t()
}
```

`:source` is the template text as it was compiled. `:parsed` is the parse
tree the underlying Liquid parser produced. `:defaulted` is the set of
source positions whose value is guarded by a `default` filter, which is what
lets a render tell an optional field that was answered by its default from a
value that is genuinely missing.
