CEL.Field (CEL v0.2.0)

A field of a message type, as a CEL.TypeProvider describes it.

:name — the field's name, as expressions select it.
:type — its CEL.Type.t/0: a list type for a repeated field, a map type for a map field, and the CEL type of a well-known type, such as :timestamp or {:wrapper, :int}, for a field holding one.
:kind — :singular, :repeated or :map.
:oneof — the name of the oneof the field is in, or nil.
:ref — the provider's own handle on the field. CEL keeps it in checked expressions and hands it back when reading the field, and never looks inside.

The checker looks a field up once, with CEL.TypeProvider.find_field/3, and evaluation reads it through the same struct.
