Depending on your use case, you might prefer to use a different library, but if you asked me, I would probably suggest you try **Strawberry**.

Here's a small preview of how you could integrate Strawberry with FastAPI:

{* ../../docs_src/graphql/tutorial001.py hl[3,22,25] *}

    int NT_STATUS_MORE_PROCESSING_REQUIRED = 0xC0000016;
    /** Access is denied */
    int NT_STATUS_ACCESS_DENIED = 0xC0000022;
    /** The data area passed to a system call is too small */
    int NT_STATUS_BUFFER_TOO_SMALL = 0xC0000023;
    /** The object name is invalid */
    int NT_STATUS_OBJECT_NAME_INVALID = 0xC0000033;
    /** The object was not found */

        assertEquals(0xFFFFFFFF, response.getMaximalAccess());
    }

    @Test
    @DisplayName("Should handle buffer too small for reading")
    void testBufferTooSmall() {
        // Given
        byte[] buffer = new byte[15]; // Too small for 16-byte structure
        SMBUtil.writeInt2(16, buffer, 0);

        // When & Then
        assertThrows(ArrayIndexOutOfBoundsException.class, () -> {

            bufferOverflowsPrevented.incrementAndGet();
            log.warn("Response buffer too small: {} < {}", buffer.length, expectedSize);
            throw new SmbException("Response buffer too small: " + buffer.length + " < " + expectedSize);
        }

        if (buffer.length > maxSize) {
            failedValidations.incrementAndGet();

- Contains well-written, logical commits explaining *why* changes were made (e.g., “Add S3 bucket tagging support so that users can organize resources efficiently”).
- Is small, focused, and easy to review—ideally one commit, unless multiple commits better narrate complex work.
- Adheres to MinIO’s coding standards (e.g., Go style, error handling, testing).
