//! Catalog trait implementation for IcebergRestCatalog
//!
//! This module bridges the Catalog trait with the implementation methods.
//! Uses conditional compilation to handle Send requirements for native vs WASM.

use super::IcebergRestCatalog;
use async_trait::async_trait;

// Single trait implementation that works for both native and WASM
// The only difference is whether the async trait requires Send
#[cfg_attr(not(target_family = "wasm"), async_trait)]
#[cfg_attr(target_family = "wasm", async_trait(?Send))]
