Struct VectorUpdateInfo 

pub struct VectorUpdateInfo {
    pub version: u64,
    pub data: Vec<u8>,
    pub prev: Option<Box<VectorUpdateInfo>>,
}

The commit timestamp at which this update takes effect.

data: Vec<u8>

The serialized value that this update replaced (for undo / snapshot reads).

prev: Option<Box<VectorUpdateInfo>>

Link to the previous (older) version in the chain.
