//! Platform abstraction for druid toolkit.
//!
//! `druid-shell` is an abstraction around a given platform UI & application
//! framework. It provides common types, which then defer to a platform-defined
//! implementation.
//!
//! # Env
//!
//! For testing and debugging, `druid-shell` can change its behavior based on environment
//! variables. Here is a list of environment variables that `druid-shell` supports:
//!
//! - `DRUID_SHELL_DISABLE_X11_PRESENT`: if this is set and `druid-shell` is using the `x11`
//! backend, it will avoid using the Present extension.

#![warn(broken_intra_doc_links)]
#![allow(clippy::new_without_default)]
#![deny(clippy::trivially_copy_pass_by_ref)]

// Rename `gtk_rs` back to `gtk`.
// This allows us to use `gtk` as the feature name.
// The `target_os` requirement is there to exclude anything `wasm` like.
#[cfg(all(target_os = "linux", feature = "gtk"))]
