(key string, loc location)

// moveToHotCache moves a buffer from the cold to the hot cache.
// loc represents the location of the buffer in the cold cache.
func (c *BufferCache) moveToHotCache(key string, loc location) {
	// Extract buffer and cell index from the location
	bidx, cidx := loc.coldBucketIdx(), loc.coldCellIdx()

	// Retrieve the log line
	l, compressed := c.cold.buckets[bidx].get(cidx)
	// Clear the corresponding cell in the bitmap
	c.cold.buckets[bidx].freecells.clearBit(cidx)
	c.putInHot(key, l, compressed)
	c.m.m[key] = hotCacheLocation
