= SRML The Substrate Runtime Module Library (SRML) is a collection of runtime modules. == What are runtime modules? A Substrate runtime can be composed of several smaller components for separation of concerns. These components are called runtime _modules_. Each runtime module packages together a set of functions (dispatchable extrinsic calls, public or private, mutable or immutable), storage items, and events. There are four primary components that support runtime modules: === system module https://github.com/paritytech/substrate/tree/master/srml/system[`system`] provides low-level APIs and utilities for other modules. https://github.com/paritytech/substrate/tree/master/srml/system[`system`] also defines all core types and extrinsic events for the Substrate runtime. *All modules depend on the system module.* === executive module https://github.com/paritytech/substrate/tree/master/srml/executive[`executive`] dispatches incoming extrinsic calls to the respective modules in the runtime. === support macros https://github.com/paritytech/substrate/tree/master/srml/support[`support` macros] are a collection of Rust macros to facilitate the implementation of common module components. https://github.com/paritytech/substrate/tree/master/srml/support[`support` macros] expand at runtime to generate types (e.g. `Module`, `Call`, `Store`, `Event`) which are thereafter used by the runtime to communicate with the modules. Common support macros include https://crates.parity.io/srml_support/macro.decl_module.html[`decl_module`], https://crates.parity.io/srml_support_procedural/macro.decl_storage.html[`decl_storage`], https://crates.parity.io/srml_support/macro.decl_event.html[`decl_event`], and https://crates.parity.io/srml_support/macro.ensure.html[`ensure`]. === runtime The runtime expands the support macros to get type and trait implementations for each module before calling https://github.com/paritytech/substrate/tree/master/srml/executive[`executive`] to dispatch calls to the individual modules. To see an example of how this might look, see https://github.com/paritytech/substrate/blob/master/node/runtime/src/lib.rs[`../node/runtime`].
