Struct SchemaMutation 

pub struct SchemaMutation {
    pub deleted: Vec<String>,
    pub clp: Option<ClassLevelPermissions>,
    pub set_fields: Vec<SetField>,
}

A PUT /schemas/:className reduced to the work the caller has to do.

#[must_use], and deleted is not an Option. Both are deliberate: a caller that applies added and forgets deleted leaves a class carrying a field the client believes it removed, and the field then reappears in every response.

Fields

deleted: Vec<String>

Fields to drop, with their rows’ columns and, for a Relation, its join collection.

clp: Option<ClassLevelPermissions>

None means the body carried no classLevelPermissions at all, which upstream treats as “leave the stored block alone” (setPermissions returns early on undefined, SchemaController.js:1097-1099). It is not the same as an empty block, which replaces the stored one.

set_fields: Vec<SetField>

Every submitted field that is not a delete, in body order, with the options it carried.

Includes fields that already exist, and includes empty option sets, because both are meaningful. Upstream reaches enforceFieldExists for every submitted field, not only the new ones (SchemaController.js:930-934), and resubmitting a field without the options it was stored with is how a client clears them: updateFieldOptions writes whatever is left after type and targetClass are removed, which for {"type":"String"} is {} (MongoSchemaCollection.js:284-297).
