This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.

Takusen is a DBMS access library. Like HSQL and HDBC, we support
arbitrary SQL statements (currently strings, extensible to anything
that can be converted to a string).
Takusen's unique selling point is safety and efficiency.
We statically ensure all acquired database resources - such
as cursors, connections, and statement handles - are released, exactly
once, at predictable times. Takusen can avoid loading the whole result
set in memory, and so can handle queries returning millions of rows in
constant space. Takusen also supports automatic marshalling and
unmarshalling of results and query parameters. These benefits come
from the design of query result processing around a left-fold
enumerator.
Currently we fully support ODBC, Oracle, Sqlite, and PostgreSQL.
