fission 0.1.0

//! # Fission
//!
//! A cross-platform, GPU-accelerated UI framework for Rust.
//!
//! This crate re-exports all Fission sub-crates so applications only need
//! a single dependency:
//!
//! ```toml
//! [dependencies]
//! fission = { path = "..." }
//! ```
//!
//! Then use via:
//! ```rust,ignore
//! use fission::prelude::*;           // Common widget + action types
//! use fission::core::*;              // Low-level runtime/action APIs
//! use fission::widgets::*;           // Authoring widgets (Modal, Popover, etc.)
//! use fission::ir::*;                // Intermediate representation
//! use fission::theme::*;             // Theming
//! use fission::icons::material::*;   // Material icons
//! use fission::shell::DesktopApp;    // Desktop shell
//! use fission::macros::Action;       // Derive macros
//! use fission::text_engine::*;       // Rope-backed text buffer
//! ```
