Azure Storage Blob Service REST API: Sample code to get Blob Service Stats Rust

// Azure Blob Service Example: Get Blob Service Stats

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// ---- IMPORTANT ----
// The "-secondary" suffix is required.
// This requires an Azure storage account with replication set to "Read-access geo-redundant storage (RA-GRS)"
// If you made the change just prior to testing this example, you'll need to give it time for the 
// DNS to become available..  
// ---- IMPORTANT ----
