engawa 0.1.2

Engawa (縁側) — typed render-graph IR for pleme-io GPU consumers. Bevy-inspired render-graph design distilled to mado-shaped needs: no ECS, no game loop, no asset pipeline. Pure-data IR + topo sort + cycle detection + integration with garasu's headless GPU primitives.

//! Pass kinds — what wgpu encoder dispatch a node compiles to.
//!
//! Bevy's render graph distinguishes raster passes from compute
//! passes from blits because each takes a different wgpu API
//! call. Engawa keeps that distinction; the compiler routes to
//! the right encoder method.
