Standard library ################ The :mod:`amaranth.lib` module, also known as the standard library, provides modules that falls into one of the three categories: 1. Modules that will used by essentially all idiomatic Amaranth code, and are necessary for interoperability. This includes :mod:`amaranth.lib.enum` (enumerations), :mod:`amaranth.lib.data` (data structures), and :mod:`amaranth.lib.wiring` (interfaces and components). 2. Modules that abstract common functionality whose implementation differs between hardware platforms. This includes :mod:`amaranth.lib.cdc`, :mod:`amaranth.lib.memory`. 3. Modules that have essentially one correct implementation and are of broad utility in digital designs. This includes :mod:`amaranth.lib.coding`, :mod:`amaranth.lib.fifo`, and :mod:`amaranth.lib.crc`. As part of the Amaranth backwards compatibility guarantee, any behaviors described in these documents will not change from a version to another without at least one version including a warning about the impending change. Any nontrivial change to these behaviors must also go through the public review as a part of the `Amaranth Request for Comments process `_. The Amaranth standard library is separate from the Amaranth language: everything provided in it could have been implemented in a third-party library. .. toctree:: :maxdepth: 2 stdlib/enum stdlib/data stdlib/wiring stdlib/memory stdlib/cdc stdlib/coding stdlib/fifo stdlib/crc
