DatasourceFieldName
Wrapper struct to force a bit of a reflection whether or not the string passed to the write arguments is the data source field name, not the model field name. Also helps to avoid errors with convenient from-field conversions.
FieldPath
NativeUpsert
NestedWrite
RecordFilter
A wrapper struct allowing to either filter for records or for the core to communicate already known record selectors to connectors.
WriteArgs
WriteArgs represent data to be written to an underlying data source.

Enums

AggregationResult
Result of an aggregation operation on a model or field. A Field return type is only interesting for aggregations involving group bys, as they return field values alongside group aggregates.
AggregationSelection
Selections for aggregation queries.
CompositeWriteOperation
ScalarWriteOperation
UpdateType
When we write a single record using this update_records function, we always want the id of the changed record back. Even if the row wasn’t updated. This can happen in situations where we could increment a null value and the update count would be zero for mysql. However when we updating any records we want to return an empty array if zero items were updated
WriteOperation
A WriteExpression allows to express more complex operations on how the data is written, like field or inter-field arithmetic.

Traits

Connection
ConnectionLike
Marker trait required by the query core executor to abstract connections and transactions into something that can is capable of writing to or reading from the database.
Connector
ReadOperations
Transaction

apply_expression
coerce_null_to_zero_value
merge_write_args
Merges the incoming write argument values into the given, already loaded, ids. Overwrites existing values.
pick_args
Picks all arguments out of args that are updating a value for a field contained in projection, as those need to be merged into the records later on.
