-/// Returns the number of hardware threads available to the program.

///
-/// This value should be considered only a hint.
+/// Parallelism is a resource. A given machine provides a certain capacity for
+/// parallelism, i.e., a bound on the number of computations it can perform
+/// simultaneously. This number often corresponds to the amount of CPUs or
+/// computer has, but it may diverge in various cases.
///
-/// # Platform-specific behavior
+/// Host environments such as VMs or container orchestrators may want to
+/// restrict the amount of parallelism made available to programs in them. This
+/// is often done to limit the potential impact of (unintentionally)
+/// resource-intensive programs on other programs running on the same machine.
///
-/// If interpreted as the number of actual hardware threads, it may undercount on
-/// Windows systems with more than 64 hardware threads. If interpreted as the
-/// available concurrency for that process, it may overcount on Windows systems
-/// when limited by a process wide affinity mask or job object limitations, and
-/// it may overcount on Linux systems when limited by a process wide affinity
-/// mask or affected by cgroups limits.
+/// # Limitations
+///
+/// The purpose of this API is to provide an easy and portable way to query
+/// the default amount of parallelism the program should use. Among other things it
+/// does not expose information on NUMA regions, does not account for
+/// differences in (co)processor capabilities, and will not modify the program's
+/// global state in order to more accurately query the amount of available
+/// parallelism.
+///
+/// Resource limits can be changed during the runtime of a program, therefore the value is
+/// not cached and instead recomputed every time this function is called. It should not be
+/// called from hot code.
+///
+/// The value returned by this function should be considered a simplified
+/// approximation of the actual amount of parallelism available at any given
+/// time. To get a more detailed or precise overview of the amount of
+/// parallelism available to the program, you may wish to use
+/// platform-specific APIs as well. The following platform limitations currently
+/// apply to `available_parallelism`:
+///
+/// On Linux:
+/// - It may overcount the amount of parallelism available when limited by a
+/// process-wide affinity mask, or when affected by cgroup limits.
+///
+/// On all targets:
+/// - It may overcount the amount of parallelism available when running in a VM
+/// with CPU usage limits (e.g. an overcommitted host).
///
/// # Errors
///
-/// This function will return an error in the following situations, but is not
-/// limited to just these cases:
+/// This function will, but is not limited to, return errors in the following
+/// cases:
///
-/// - If the number of hardware threads is not known for the target platform.

-# These exist entirely to fool aclocal when bootstrapping libtool.
-#
-# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN),
-# which have later been changed to m4_define as they aren't part of the
-# exported API, or moved to Autoconf or Automake where they belong.
-#
-# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
-# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
-# using a macro with the same name in our local m4/libtool.m4 it'll
-# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
-# and doesn't know about Autoconf macros at all.)
-#
-# So we provide this file, which has a silly filename so it's always
-# included after everything else. This provides aclocal with the
-# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
-# because those macros already exist, or will be overwritten later.
-# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
-#
-# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
-# Yes, that means every name once taken will need to remain here until
-# we give up compatibility with versions before 1.7, at which point
-# we need to keep only those names which we still refer to.
