//! `Send` and `Sync` bounds that relax on wasm with atomics.
//!
//! The name follows `wgpu_types::WasmNotSend`, which exists for the same reason. A wgpu handle is
//! `Send + Sync` on wasm only through `fragile-send-sync-non-atomic-wasm`, and that feature turns
//! itself off once atomics are on. Anything holding a device or a queue stops being `Send` in the
//! threaded web build.
//!
//! Nothing is lost. One thread in a browser touches wgpu, and nothing is sent anywhere.
