Crate once_vec 

OnceVec is a OnceCell-based grow-only vector.

It has the following properties:

• It can only grow, elements once pushed cannot be removed.
• Elements once pushed cannot be modified. (use interior mutability if you want to modify the elements)
• Pushing new elements does not require a mutable reference.
• Memory allocation happens in steps of powers of two.
• The total size is limited 1 + 2 + 4 + ... + 2^(N-1) = 2^N - 1, where N is the number of chunks, which is a const generic parameter.
• It does not implement Sync; shared concurrent access is not supported.
• Written entirely in safe rust.
