@spec before_init(:default | tuple() | list(), module()) :: {:ok, atom()}

Run the before_init methods for a store.

spec is :default, a single {method, args} tuple, or a list of such tuples. module is the module the methods are defined on (the Store or Repo).

@spec delete(any(), atom()) :: :ok | {:error, any()}

Delete the record provided.

Returns :ok for a struct matching table or for nil, and {:error, :bad_schema} when the struct does not match table.

@spec delete_expired(atom(), integer()) :: :ok

Delete every record in table whose expires_at is at or before now (milliseconds). Used by the Store/ActiveRepo sweep to reclaim memory; reads already hide expired records, so this is only about freeing them.

@spec one(map() | tuple(), atom()) :: {:ok, map()} | {:error, any()}

Get one record matching an attributes map or a match query. An expired record is treated as {:error, :not_found}.

@spec seed(binary() | nil, atom()) :: {:ok, :seed_success} | {:error, any()}

Evaluate seed_file and write its records to table.

A nil seed_file is a no-op. Returns {:ok, :seed_success} or {:error, reason}.

@spec select(map() | tuple(), atom()) :: {:ok, [map()]} | {:error, any()}

Get all records matching an attributes map or a match query.

Returns {:error, :bad_select_query} for any other query shape.

@spec withdraw(map() | tuple(), atom()) :: {:ok, map()} | {:error, any()}

Get one record matching the query, delete it, and return it. An expired record is treated as {:error, :not_found}.

@spec write(map(), atom()) :: {:ok, map()} | {:error, any()}

Write a record to table.

When the schema has a uuid field a value is generated if one is absent. When the table has a ttl the record's expires_at is stamped from the current time. Returns {:error, :bad_schema} when the struct does not match table.
