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.tA pool implementation for the current concurrency library.
module type CONNECTION = Caqti_connection_sig.S with type 'a future := 'a Lwt.tThe connection API specialized for the current concurrency library.
type connection = (module CONNECTION)Shortcut for the connection API passed as a value.
val connect :
Uri.t ->
(connection, [> Caqti_error.load_or_connect ]) result Lwt.tconnect 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 ]) resultconnect_pool uri is a pool of database connections constructed by connect uri.
val or_fail : ('a, [< Caqti_error.t ]) result -> 'a Lwt.tConverts an error to an Lwt future failed with a Caqti_error.Exn exception holding the error.
