util.bit53

util.bit53 is a compatibility library for Lua 5.3 and later where bitwise operations are operators and may no longer be available as functions.

This is not used directly but via util.bitcompat.

Currently it provides a subset of bitwise operations, namely:

band(...)

Binary AND operation

bor(...)

Binary OR operation

bxor(...)

Binary XOR operation

rshift(x, disp)

Shift right

rshift(x, disp)

Shift left

See the Lua manual for further details.
