Enum FieldChange 

pub enum FieldChange {
    Set {
        field_type: FieldType,
        options: ParseMap,
    },
    Delete,
}

What a fields entry in a schema-API body asks for.

Delete is spelled {"__op":"Delete"} on the wire and is only meaningful on PUT. Modelled as a variant rather than as a flag on a struct so that a caller enumerating the plan cannot treat a delete as a weird kind of add.

Variants

Set

Fields

field_type: FieldType

options: ParseMap

Everything the wire spec carried besides type and targetClass, verbatim.

That is exactly what upstream stores under _metadata.fields_options.<field> (MongoSchemaCollection.js:262-264, :293-295): it destructures type and targetClass off and keeps the rest, including keys it does not understand.

Delete
