Summary
Functions
Returns an inferrer function for Squirrelix.generate/3 / check/3.
Functions
@spec inferrer(Postgrex.conn()) :: Squirrelix.Inference.inferrer()
Returns an inferrer function for Squirrelix.generate/3 / check/3.
The returned function takes a Squirrelix.Query and returns
{:ok, [params: ..., returns: ...]} or {:error, structured_error}.
OID→type and column-nullability catalog lookups are memoised for the lifetime of the returned function so a generate/check pass does not re-query the same catalog rows for every parameter and column.
