What a config field is, for tooling.

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.

Expr(ValueKind)

JSONLogic resolving to the given kind.

Interpolated

A document with expression holes.

Output

A write destination.

Templated

A runtime-declared set of fields.

List(fn() -> Self)

An array of the element kind.

Map(fn() -> Self)

An object whose values are of the given kind.

Nested(fn() -> &'static [FieldSpec])

A nested config’s fields.
