//! A cross-platform graphics and compute library based on [WebGPU](https://gpuweb.github.io/gpuweb/).
//!
//! To start using the API, create an [`Instance`].
//!
//! ## Feature flags
#![doc = document_features::document_features!()]
//!
//! ### Feature Aliases
//!
//! These features aren't actually features on the crate itself, but a convenient shorthand for
//! complicated cases.
//!
//! - **`wgpu_core`** --- Enabled when there is any non-webgpu backend enabled on the platform.
//! - **`naga`** ---- Enabled when any non-wgsl shader input is enabled.
//!
