Vint: variable-length representation of integers
This module currently provides only conversions between vint and the OCaml int type. Here are the current limits of OCaml ints on 32-bit and 64-bit systems:
word length (bits) 32 64 int length (bits) 31 63 min_int (lowest signed int) 0x40000000 0x4000000000000000 -1073741824 -4611686018427387904 max_int (greatest signed int) 0x3fffffff 0x3fffffffffffffff 1073741823 4611686018427387903 lowest unsigned int 0x0 0x0 0 0 greatest unsigned int 0x7fffffff 0x7fffffffffffffff 2147483647 9223372036854775807 maximum vint length (data bits) 31 63 maximum vint length (total bytes) 5 9
Note that ints (signed) and uints use the same representation
for integers within [0,
Interpret a vint as an unsigned int.
Bi_util.Errorif the input string is not a single valid uvint that is representable using the uint type.
