                                                  Use adds the mutation hooks to all the entity clients. In order to add hooks to a specific client, call: `client.Node.Use(...)`.

                                                  type CommitFunc

                                                  type CommitFunc func(context.Context, *Tx) error

                                                    The CommitFunc type is an adapter to allow the use of ordinary function as a Committer. If f is a function with the appropriate signature, CommitFunc(f) is a Committer that calls f.

                                                    func (CommitFunc) Commit

                                                    func (f CommitFunc) Commit(ctx context.Context, tx *Tx) error

                                                      Commit calls f(ctx, m).

                                                      type CommitHook func(Committer) Committer

                                                        CommitHook defines the "commit middleware". A function that gets a Committer and returns a Committer. For example:

                                                        hook := func(next ent.Committer) ent.Committer {
                                                        	return ent.CommitFunc(func(context.Context, tx *ent.Tx) error {
                                                        		// Do some stuff before.
                                                        		if err := next.Commit(ctx, tx); err != nil {
                                                        			return err
                                                        		}
                                                        		// Do some stuff after.
                                                        		return nil
                                                        	})
                                                        }
                                                        

                                                        type Committer

                                                        type Committer interface {
                                                        	Commit(context.Context, *Tx) error
                                                        }

                                                          Committer is the interface that wraps the Committer method.

                                                          type ConstraintError

                                                          type ConstraintError struct {
                                                          	// contains filtered or unexported fields
                                                          }

                                                            ConstraintError returns when trying to create/update one or more entities and one or more of their constraints failed. For example, violation of edge or field uniqueness.

                                                            func (ConstraintError) Error

                                                            func (e ConstraintError) Error() string

                                                              Error implements the error interface.

                                                              func (*ConstraintError) Unwrap

                                                              func (e *ConstraintError) Unwrap() error

                                                                Unwrap implements the errors.Wrapper interface.
