Zero Allocation 핵심
1. Span<T> 기본
// 문자열 슬라이싱 (Heap 할당 없음)
ReadOnlySpan<char> part = text.AsSpan(0, 10);
// 배열 슬라이싱
Span<int> span = data.AsSpan();
Span<int> firstHalf = span[..^(span.Length / 2)];
2. ArrayPool<T>
// 배열 대여
var buffer = ArrayPool<byte>.Shared.Rent(size);
try
{
ProcessBuffer(buffer.AsSpan(0, size));
}
finally
{
ArrayPool<byte>.Shared.Return(buffer);
}
3. stackalloc
// Stack에 작은 버퍼 할당
Span<byte> buffer = stackalloc byte[256];
4. 주의사항
- ⚠️ Span<T>는 async-await 사용 불가
- ⚠️ ArrayPool: Rent 후 반드시 Return 호출
