pub type ServiceTypeId = [u8; 32];Expand description
Service type identifier used by the on-chain service registry.
The registry stores the identifier as a raw bytes32. By convention it holds right-padded
printable ASCII, so gvpn:exit is
0x6776706e3a657869740000000000000000000000000000000000000000000000, but the contract does not
enforce that, and any non-zero 32-byte value can appear on chain. Blokli renders the identifier
as its ASCII name when it follows the convention and as 0x-prefixed hex otherwise, so the
string fields of ServiceEntry and
ServiceTypeInfo may hold either form.
