Crate beamer_core 

beamer-core

Core abstractions for the Beamer audio plugin framework.

This crate provides platform-agnostic and format-agnostic traits that define the interface for audio plugins. It has no external dependencies, making it suitable for use in any context.

Main Traits

• Descriptor - Plugin definition (unprepared state, holds parameters)
• Processor - Core DSP processing trait (prepared state)
• Parameters - Parameter collection trait
• EditorDelegate - GUI configuration and callbacks

Types

• Size - 2D size in pixels
• Rect - Rectangle in pixels
• Buffer - Main audio I/O buffer
• AuxiliaryBuffers - Sidechain and aux bus access
• BusInfo - Audio bus configuration
• ParameterInfo - Parameter metadata
• PluginError - Error types
• MidiEvent - MIDI event types
• Transport - DAW transport/timing state
• ProcessContext - Processing context with sample rate and transport
