Module ref_row 

Zero-copy row decoding for fixed-size types.

This module provides traits and types for zero-copy decoding of database rows where all fields have fixed wire sizes. This is useful for high-performance scenarios where avoiding allocations is critical.

Requirements

• All struct fields must implement FixedWireSize
• All columns must be NOT NULL (no Option<T> support)
• Struct must use #[repr(C, packed)] for predictable layout
• Fields must use endian-aware types (e.g., I64LE instead of i64)

Example

use zerocopy::little_endian::{I64 as I64LE, I32 as I32LE};
use zero_mysql::ref_row::RefFromRow;

#[derive(RefFromRow)]
#[repr(C, packed)]
struct UserStats {
    user_id: I64LE,
    login_count: I32LE,
}
