Crate zennode 

Self-documenting node definitions for image processing pipelines.

zennode provides a trait-based system for defining pipeline operations with full parameter schemas, RIAPI querystring parsing, and JSON Schema generation — all with permanent backwards compatibility.

Quick Start

use zennode::*;

#[derive(Node, Clone, Debug, Default)]
#[node(id = "myfilter.brightness", group = Tone, role = Filter)]
pub struct Brightness {
    /// Amount of brightness adjustment
    #[param(range(-1.0..=1.0), default = 0.0, identity = 0.0, step = 0.05)]
    #[param(unit = "", section = "Main")]
    pub amount: f32,
}

Features

• derive (default) — enables #[derive(Node)] and #[derive(NodeEnum)]
• std (default) — enables std::error::Error impl
• serde — enables serde Serialize/Deserialize on param types
• json-schema — enables JSON Schema generation (implies serde)
