Class type
module Bus : sig ... end

An Async extension of Core_kernel.Bus. Functions that share the same name and types as those in Core_kernel.Bus are direct calls to the same.

module Command : sig ... end

Async.Command is Core.Command with additional Async functions.

module Cpu_usage : sig ... end

Simple cpu usage statistics.

module Dynamic_port_writer : sig ... end

For communicating a dynamically chosen TCP port from a child process to its parent.

module File_tail : sig ... end

File_tail is useful for pulling data from a file that is being appended to by another process. Creating a file tail returns the reader half of a pipe whose writer half is populated by a background process that roughly does the following loop.

module File_writer : sig ... end

File_writer is a thin wrapper around Writer with a couple of extra features:

module Lock_file : sig ... end

Async.Lock_file is a wrapper that provides Async equivalents for Core.Lock_file.

module Persistent_connection : sig ... end
module Persistent_connection_intf : sig ... end
module Persistent_singleton : sig ... end
module Rpc : sig ... end

This module just re-exports lots of modules from Async_rpc_kernel and adds some Unix-specific wrappers in Connection (for using Reader, Writer, and Tcp). For documentation, see Rpc and Connection_intf in the Async_rpc_kernel library.

module Schedule_v5 : sig ... end
module Schedule_v4_deprecated : sig ... end
module Sequencer_table : sig ... end

A table of sequencers indexed by key, so that at any moment for each key there is at most one job running.

module Tcp : sig ... end

Tcp supports connection to inet sockets and unix sockets. These are two different types. We use 'a Where_to_connect.t to specify a socket to connect to, where the 'a identifies the type of socket.

module Tcp_file : sig ... end

Access to on-disk files in parallel with serving them over a TCP connection.

module Typed_tcp : sig ... end
module Udp : sig ... end

A grab-bag of performance-oriented, UDP-oriented network tools. These provide some convenience, but they are more complex than basic applications require.

module Unpack_sequence : sig ... end

Unpack_sequence uses an Unpack_buffer.t to unpack a sequence of packed values coming from a string Pipe.Reader.t or a Reader.t. It can produce a pipe of upacked values or iterate a user-supplied function over the unpacked values.

module User_and_group : sig ... end

Wrapper around Core.User_and_group with a deferred for_this_process / for_this_process_exn.

module Versioned_rpc = Async_rpc_kernel.Versioned_rpc
module Versioned_typed_tcp : sig ... end
module Weak_hashtbl : sig ... end

Like Core.Weak_hashtbl, but automatically collects keys with unused data, rather than requiring user code to call remove_keys_with_unused_data.
