A cpp ownership/borrowing library

🌈 Friendship

What it is?

It's an implementation of adapted borrowing/ownershipping. The goal is to replace pointers and make a safer alternative by:

• only the actual owner can change the value if is mutable
• only one mutable borrow can occur and any other
• multiple immutable borrows can occur (read-only)
• the owner that made a mutable borrow loses even the right to read the value
• a borrow from an immutable borrow is the same as borrowing as immutable directly from the original owner
• if an illegal borrow occurs it creates a new independent value instead and throws an error

Errors

What if the owner is deleted?

An error is thrown and the children are becoming new owners to avoid errors.

Creating a value with a nullptr source in the constructor

It would return a value like a normal one but with a default value (RIP if it's immutable) and an error is thrown.

Datatypes support

Our goal is to create a fully secure environment to code and for this, we recreate all the must of types:

• int
  • 16
  • 32
  • 64
  • 128
• float
  • 16
  • 32
  • 64
  • 128
• unicode char
• bool
• dynamic
  • string
  • vector
  • array
• struct
• implementations
