build(Keyword.t()) :: {atom(), Keyword.t()}

Passes the given keyword list to Ash.Query.build/2 with the query being prepared.

This allows declaring simple query modifications in-line. For more complicated query modifications, use a custom preparation.

For example:

read :top_ten_songs do
  prepare build(sort: [song_rank: :desc], limit: 10)
end

Specs

set_context(map() | (Ash.Query.t() -> mfa())) :: {atom(), Keyword.t()}

The MFA should return {:ok, context_to_be_merged} or {:error, term}
