Types

type ArchiveFunc 

type ArchiveFunc func(context.Context, *ent.ArchiveMutation) (ent.Value, error)

The ArchiveFunc type is an adapter to allow the use of ordinary function as Archive mutator.

func (Chain) Append 

func (c Chain) Append(hooks ...ent.Hook) Chain

Append extends a chain, adding the specified hook as the last ones in the mutation flow.

func (Chain) Extend 

func (c Chain) Extend(chain Chain) Chain

Extend extends a chain, adding the specified chain as the last ones in the mutation flow.

func (Chain) Hook 

func (c Chain) Hook() ent.Hook

Hook chains the list of hooks and returns the final hook.
