#[repr(transparent)]pub struct PeerId(pub NonZero<U256>);Expand description
PeerId is a unique identifier for a peer. This represents a 256-bit number that can be compared, sorted, and hashed rather than an address or random byte sequence. Ideally, this is generated when the node peer is created and never changes. 256-bits is more than enough to guarantee uniqueness. So why 256-bits? Most protocols operate on ECC-scalars which are at least 256-bits. This allows us to use the same data type for the peer id and the ECC scalar.
