exception camcops_server.cc_modules.cc_proquint.InvalidProquintException[source]
camcops_server.cc_modules.cc_proquint.int_from_proquint(proquint: str) → int[source]

Convert proquint string into integer.

Parameters

proquint – string to decode

Returns

converted integer value

camcops_server.cc_modules.cc_proquint.proquint_from_int(int_value: int, size_in_bits: int) → str[source]

Convert integer value into proquint

>>> proquint_from_int(0x493b05ee, 32)
hohur-bilov

0x493b05ee in binary is:
0100 1001 0011 1011 - 0000 0101 1110 1110

Parameters

  • int_value – integer value to encode

  • size_in_bits – size of integer in bits (must be a multiple of 16)

Returns

proquint string identifier

camcops_server.cc_modules.cc_proquint.proquint_from_uuid(uuid_obj: uuid.UUID) → str[source]

Convert UUID to proquint (via the UUID’s 128-bit integer representation).

camcops_server.cc_modules.cc_proquint.uuid_from_proquint(proquint: str) → uuid.UUID[source]

Convert proquint to UUID.
