Procedural macros for the BridgeRust framework.

Website: bridgerust.dev

Overview

This crate provides the core macros used to expose Rust code to Python and Node.js. It is re-exported by the main bridgerust crate and should generally not be used directly.

Macros

#[export]

Marks a function, struct, or impl block for export to Python and Node.js.

use bridgerust::export;

#[export]
pub fn greet(name: String) -> String {
    format!("Hello, {}!", name)
}

#[constructor]

Marks a method within an impl block as the constructor (__init__ in Python, constructor in JS).

use bridgerust::export;

#[export]
pub struct Client {
    url: String,
}

#[export]
impl Client {
    #[constructor]
    pub fn new(url: String) -> Self {
        Self { url }
    }
}

#[error]

Registers a custom error type for cross-language error handling.
