Struct datatypes::VarInt

pub struct VarInt(/* private fields */);

A wrapper struct for a signed 32-bit value, typically used for implementing DataReader and DataWriter. But the writen size of this type can vary based on the size of the data.

Variable-length format such that smaller numbers use fewer bytes. The 7 least significant bits are used to encode the value and the most significant bit indicates whether there’s another byte after it for the next part of the number. The least significant group is written first, followed by each of the more significant groups; thus, VarInts are effectively little endian (however, groups are 7 bits, not 8).

VarInts are never longer than 5 bytes
