Go - The Ultimate Folder Structure

Organizing your Go (Golang) project's folder structure can help improve code readability, maintainability, and scalability. While there is no one-size-fits-all structure, here's a common folder structure for a Go project:

project-root/
    ├── cmd/
    │   ├── your-app-name/
    │   │   ├── main.go         # Application entry point
    │   │   └── ...             # Other application-specific files

And upgradable read write lock for go

UpgradableRWMutex is an enhanced version of the standard sync.RWMutex. It has the all methods sync.RWMutex with exact same semantics. It gives more methods to give upgradable-read feature.

The new semantics for upgradable-read are as follows:

• Multiple goroutines can get read-lock together with a single upgradable-read-lock.
• Only one goroutine can have a write-lock and no read-lock/upgradable-read-lock can be acquired in this state.
