Connecting with Lwt.

This module contains the signature and connect function specialized for use with Lwt.

include Caqti_connect_sig.S with type 'a future := 'a Lwt.t
module Pool : Caqti_pool_sig.S with type 'a future := 'a Lwt.t

A pool implementation for the current concurrency library.

module type CONNECTION = Caqti_connection_sig.S with type 'a future := 'a Lwt.t

The connection API specialized for the current concurrency library.

type connection = (module CONNECTION)

Shortcut for the connection API passed as a value.

connect uri locates and loads a driver which can handle uri, passes uri to the driver, which establish a connection and returns a first-class module implementing Caqti_connection_sig.S.

val connect_pool : ?max_size:int -> Uri.t -> ((connection, [> Caqti_error.connect ]) Pool.t, [> Caqti_error.load ]) result

connect_pool uri is a pool of database connections constructed by connect uri.

val or_fail : ('a, [< Caqti_error.t ]) result -> 'a Lwt.t

Converts an error to an Lwt future failed with a Caqti_error.Exn exception holding the error.
