//! `@react-native-gpui/fs`: a Node-shaped file API for the desktop app.
//!
//! The TypeScript spec in `../src/NativeFs.ts` is the contract; the generator
//! turns it into the `NativeFsSpec` trait implemented here. That trait is the
//! only thing the C++ bridge knows about, so the API surface is edited there and
//! regenerated, never in this file.
//!
//! Rust needs a trait's methods in a single `impl` block, so this file holds that
//! block and hands each method to a helper in the file that owns the concern:
//!
//! - `files` — reading, writing, copying, truncating, permissions and times
//! - `dirs` — listing, creating, removing and `mkdtemp`
//! - `handles` — open descriptors, positioned reads and writes
//! - `links` — symbolic links, `realpath` and `access`
//! - `paths` — the well-known folders, created on first read
//! - `dialogs` — the pickers, `reveal` and `openExternal`
//! - `watching` — the watcher behind `watch` and `unwatch`
//!
//! Keeping the bodies in those files is what makes the crate readable; keeping
//! the `impl` here is what makes it compile.
