Types

type ModuleDB

type ModuleDB interface {
	ormtable.Schema

	// DefaultJSON writes default JSON for each table in the module to the target.
	DefaultJSON(ormjson.WriteTarget) error

	// ValidateJSON validates JSON for each table in the module.
	ValidateJSON(ormjson.ReadSource) error

	// ImportJSON imports JSON for each table in the module which has JSON
	// defined in the read source.
	ImportJSON(context.Context, ormjson.ReadSource) error

	// ExportJSON exports JSON for each table in the module.
	ExportJSON(context.Context, ormjson.WriteTarget) error
}

ModuleDB defines the ORM database type to be used by modules.

func NewModuleDB

func NewModuleDB(schema *ormv1alpha1.ModuleSchemaDescriptor, options ModuleDBOptions) (ModuleDB, error)

NewModuleDB constructs a ModuleDB instance from the provided schema and options.

type ModuleDBOptions

type ModuleDBOptions struct {
	// TypeResolver is an optional type resolver to be used when unmarshaling
	// protobuf messages. If it is nil, protoregistry.GlobalTypes will be used.
	TypeResolver ormtable.TypeResolver

	// FileResolver is an optional file resolver that can be used to retrieve
	// pinned file descriptors that may be different from those available at
	// runtime. The file descriptor versions returned by this resolver will be
	// used instead of the ones provided at runtime by the ModuleSchema.
	FileResolver protodesc.Resolver

	// JSONValidator is an optional validator that can be used for validating
	// messaging when using ValidateJSON. If it is nil, DefaultJSONValidator
	// will be used
	JSONValidator func(proto.Message) error

	// GetBackendResolver returns a backend resolver for the requested storage
	// type or an error if this type of storage isn't supported.
	GetBackendResolver func(ormv1alpha1.StorageType) (ormtable.BackendResolver, error)
}

ModuleDBOptions are options for constructing a ModuleDB.
