supabase-client-realtime 0.2.1

//! Supabase Realtime WebSocket client.
//!
//! This crate implements the Phoenix Channels v1.0.0 protocol to provide
//! real-time subscriptions for Postgres changes, broadcast messages, and
//! presence tracking.
//!
//! # Usage
//!
//! ```ignore
//! use supabase_client_sdk::prelude::*;
//!
//! let realtime = client.realtime()?;
//! realtime.connect().await?;
//!
//! let channel = realtime.channel("db-changes")
//!     .on_postgres_changes(
//!         PostgresChangesEvent::Insert,
//!         PostgresChangesFilter::new("public", "messages"),
//!         |payload| println!("New row: {:?}", payload.record),
//!     )
//!     .subscribe(|status, _err| println!("Status: {}", status))
//!     .await?;
//! ```
