func Attach(ctx context.Context, hashes Hashes) context.Context

func Calculate

func Calculate(ctx context.Context) (context.Context, error)

Calculate determines the hashes migrations and attaches them to the context.

*

• Each file name is hashed along with the hash of the previous file name;
• This means that if any file is added, removed, or renamed it will break
• the hash chain and invalidate any database that was created after.
• The file contents is then hashed with the chained file name hash; This means that if the contents of a file changes, it will invalidate the database only for that migration, but not any subsiquent databases.
