//! Types and functions which define our public api and their
//! helper functionality.
//!
//! # Conventions
//!
//! Each major type gets its own module. The module is laid out as follows:
//!
//! - The type itself
//! - `impl` block for the type
//! - `Drop` implementation for the type (if needed)
//! - Descriptor types and their subtypes.
//! - Any non-public helper types or functions.
//!
//! # Imports
//!
//! Because our public api is "flat" (i.e. all types are directly under the `wgpu` module),
//! we use a single `crate::*` import at the top of each module to bring in all the types in
//! the public api. This is done to:
//! - Avoid having to write out a long list of imports for each module.
//! - Allow docs to be written naturally, without needing to worry about needing dedicated doc imports.
//! - Treat wgpu-types types and wgpu-core types as a single set.
