Struct ConnectionToken 

pub struct ConnectionToken {
    pub client_id: u64,
    pub server_key: [u8; 16],
    pub expires_at: u64,
}

Opaque token issued by the auth server, embedded in the Connect packet.

The server verifies client_id matches server_key HMAC and that expires_at (Unix seconds) has not elapsed.

Fields

client_id: u64

server_key: [u8; 16]

expires_at: u64

Implementations

impl ConnectionToken

pub const SIZE: usize = 32

pub fn new(client_id: u64, server_key: [u8; 16], expires_at: u64) -> Self

pub fn to_bytes(&self) -> [u8; 32]

Serialize to exactly 32 bytes.

pub fn from_bytes(b: &[u8]) -> Result<Self, ProtocolError>

Deserialize from 32 bytes.

pub fn is_valid(&self, now_secs: u64) -> bool

Returns true when the token has not expired relative to now_secs.

pub fn checksum(&self) -> u32

Produce a simple 4-byte checksum used to verify the key field. Real deployments should use HMAC-SHA256; this is a stand-in.

Trait Implementations

impl Clone for ConnectionToken

fn clone(&self) -> ConnectionToken

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ConnectionToken

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ConnectionToken

fn eq(&self, other: &ConnectionToken) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
