An typo in CacheLib docs

[skyelves]

There is an typo in https://cachelib.org/docs/Cache_Library_User_Guides/Write_data_to_cache#write-data-to-allocated-memory-and-insert-item-handle-into-cache.

string data("new data");
// Allocate memory for the data.
auto item_handle = cache->allocate(pool_id, "key2", data.size());

// Write the data to the cache.
std::memcpy(handle->getMemory(), data.data(), data.size());

There is no handle but item_handle. Therefore, std::memcpy(handle->getMemory(), data.data(), data.size()); should be changed to std::memcpy(item_handle->getMemory(), data.data(), data.size());

Thank you for pointing out! Fix is on the way.
