Module Caqti_blockingSource
Blocking API based on the Unix module.
Warning: This module is not well tested. Please report any issues.
This module implements a blocking API. It is not designed for preemptive threading. That is, connections and connection pools must be created and used within a single thread, and any limitation on multithreading from the driver or client library applies.
You can use a connection pool to cache a single DB connection, additional connections will not be allocated, since usage is serial.
include Caqti_connect_sig.S with type 'a future = 'a
The type of a deferred value of type 'a.
A pool implementation for the current concurrency library.
The connection API specialized for the current concurrency library.
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 ]) resultconnect_pool uri is a pool of database connections constructed by connect uri.
Takes Ok x to x and raises Caqti_error.Exnerr on Error err.
