Crate truce_gui 

Built-in GUI for truce plugins.

Orchestrates the two truce_gui_types::RenderBackend impls into editor types: with the default cpu feature, BuiltinEditor rasterises widgets to a truce_cpu::CpuBackend (tiny-skia) pixmap and blits it to a wgpu surface; with the gpu feature, GpuEditor renders directly through truce_gpu::WgpuBackend. The non-runtime data types (layout, widget regions, interaction state, theme, render trait) live in truce-gui-types and the plugin traits in truce-plugin; this crate re-exports them so existing truce_gui::... paths keep working.

Re-exports

pub use editor::BuiltinEditor;

pub use platform::EditorScale;

Modules

blit

Pixel buffer → wgpu surface blit pipeline.

editor

Built-in editor using the CPU render backend.

font

Font rendering using fontdue (TrueType rasterization).

interaction

BaseviewTranslator - the windowing-toolkit-specific half of truce-gui’s interaction surface. The platform-agnostic data types (InputEvent, MouseButton, Modifiers, WidgetRegion, InteractionState, DragState, DropdownState, dispatch, …) live in truce_gui_types::interaction and are re-exported here so existing truce_gui::interaction::* paths keep working.

layout

Simple layout helpers for positioning widgets.

platform

Platform window bridging for baseview.

render

Render backend trait for abstracting over CPU and GPU rendering.

snapshot

Read-only view of parameter state consumed by the pure-library rendering and interaction functions (widgets::draw, interaction::dispatch).

theme

widgets

Audio plugin UI widgets: knobs, sliders, toggles, labels, headers.

Macros

layout

Declarative layout DSL for plugin GUIs.

Structs

CpuBackend

CPU-based rendering backend.

ImageId

Opaque handle to a backend-registered image.

ParamSnapshot

Immutable view of one frame’s worth of parameter state.

Theme

Visual theme for the built-in GUI.

Traits

ColorExt

Extension trait giving truce_gui_types::theme::Color the to_skia / to_premultiplied methods. Lives here (next to the tiny-skia rasterizer that consumes them) so truce-gui-types stays rasterizer-free.

IntoLayoutEditor

Fluent shorthand for default_editor. Build a GridLayout, then close the editor() impl with .into_editor(&self.params):

PluginLogic

The f32-buffer user-facing plugin trait.

PluginLogic64

The f64-buffer user-facing plugin trait. Same surface as PluginLogic but with the audio buffer pinned to f64.

PluginLogicCore

Wrapper-facing plugin trait, generic over the audio sample type.

RenderBackend

Abstraction over rendering backends (CPU via tiny-skia, GPU via wgpu).

Functions

backing_scale

Get the display scale factor used to size the next editor.

default_editor

Construct truce’s default editor for a plugin’s editor() impl.

default_hit_test

Default hit test: circular for knobs, rectangular for everything else, skip meters. Used by the leaf traits’ hit_test defaults.

to_physical_px

Convert a logical extent (in points) to physical pixels.
