Actually, all (or most) of the web frameworks work in this same way.

You never call those functions directly. They are called by your framework (in this case, **FastAPI**).

///

#### Return *enumeration members* { #return-enumeration-members }

You can return *enum members* from your *path operation*, even nested in a JSON body (e.g. a `dict`).

They will be converted to their corresponding values (strings in this case) before returning them to the client:

{* ../../docs_src/path_params/tutorial005_py310.py hl[18,21,23] *}

In your client you will get a JSON response like:

	}{ID: id})
	if err != nil {
		writeErrorResponseJSON(ctx, w, toAPIError(ctx, err), r.URL)
		return
	}

	writeSuccessResponseJSON(w, b)
	// Notify peers to load rebalance.bin and start rebalance routine if they happen to be
	// participating pool's leader node
	globalNotificationSys.LoadRebalanceMeta(ctx, true)
}

func (a adminAPIHandlers) RebalanceStatus(w http.ResponseWriter, r *http.Request) {
	ctx := r.Context()

    C getColumnKey();

    /** Returns the value of this cell. */
    @ParametricNullness
    V getValue();

    /**
     * Compares the specified object with this cell for equality. Two cells are equal when they have
     * equal row keys, column keys, and values.
     */
    @Override
    boolean equals(@Nullable Object obj);

    /**
     * Returns the hash code of this cell.
     *

Best practice is to set conventions in a plugin (2). This keeps the underlying object "dumb", so it can be reused in multiple contexts and doesn't contain any special information about how conventions are calculated or what they could be.  In the wild, we've seen some objects set conventions in the object's constructor (3), but this can lead to unexpected assumptions or coupling between plugins.

            // Assert
            assertNotNull(unwrapped);
            assertTrue(unwrapped instanceof DosFileFilter);

            // Verify fields preserved (via reflection since they are protected)
            var wildcardField = DosFileFilter.class.getDeclaredField("wildcard");
            wildcardField.setAccessible(true);
            var attributesField = DosFileFilter.class.getDeclaredField("attributes");

		}
		if err := tw.writeRawFile(name, data, flag, FormatPAX); err != nil || isGlobal {
			return err // Global headers return here
		}
	}

	// Pack the main header.
	var f formatter // Ignore errors since they are expected
	fmtStr := func(b []byte, s string) { f.formatString(b, toASCII(s)) }
	blk := tw.templateV7Plus(hdr, fmtStr, f.formatOctal)
	blk.setFormat(FormatPAX)
