Module connection 

MySQL connection implementation.

This module implements the MySQL wire protocol connection, including connection establishment, authentication, and state management.

Current Status

Synchronous implementation complete. The async Connection trait from sqlmodel_core is not yet implemented. Current API uses _sync suffix methods.

Migration Path to Async

To implement the Connection trait, these changes are needed:

1. Replace std::net::TcpStream with asupersync::net::TcpStream
2. Convert read_packet/write_packet to async with .await
3. Add &Cx context parameter to all async methods
4. Return Outcome<T, E> instead of Result<T, E>
5. Add cancellation checks via cx.checkpoint()?

See crates/sqlmodel-mysql/README.md for the full roadmap.

Synchronous API

let mut conn = MySqlConnection::connect(config)?;
let rows = conn.query_sync("SELECT * FROM users WHERE id = ?", &[Value::Int(1)])?;
conn.close()?;

Structs

MySqlConnection

MySQL connection.

ServerCapabilities

Server capabilities received during handshake.

Enums

ConnectionState

Connection state in the MySQL protocol state machine.
