Crate venus 

Venus: A reactive notebook environment for Rust.

Venus provides an interactive notebook experience with:

• Reactive execution: Cells automatically re-execute when dependencies change
• Full IDE support: Uses .rs files, so rust-analyzer works out of the box
• Fast compilation: Cranelift JIT for sub-second feedback
• Hot reload: Modify code without losing state

Quick Start

use venus::prelude::*;

/// Load configuration
#[venus::cell]
pub fn config() -> Config {
    Config::default()
}

/// Process data using config
#[venus::cell]
pub fn process(config: &Config) -> Result<Data, Error> {
    // config is automatically passed from the config() cell
    load_and_process(&config.path)
}

Cell Dependencies

Dependencies are inferred from function parameters:

• fn foo(x: &T) depends on a cell that returns T
• fn bar(a: &A, b: &B) depends on cells returning A and B

The parameter name must match the producing cell’s function name.
