Struct SessionId 

pub struct SessionId(/* private fields */);

Unique identifier for a session instance.

Generated by XOR-ing a hash of the operator ID with a monotonic counter, ensuring uniqueness within and across operators.

Implementations

impl SessionId

pub fn generate(operator_id: &str, counter: &AtomicU64) -> Self

Generates a new unique session ID.

Combines a hash of the operator ID with a monotonic counter to produce IDs that are unique across operators and invocations.

pub fn to_bytes(self) -> [u8; 8]

Serializes this session ID to a big-endian byte array.

pub fn from_bytes(bytes: &[u8]) -> Option<Self>

Deserializes a session ID from a big-endian byte slice.

Returns None if the slice is not exactly 8 bytes.

pub fn as_u64(self) -> u64

Returns the raw u64 value.

Trait Implementations

impl Archive for SessionId

where u64: Archive,

const COPY_OPTIMIZATION: CopyOptimization<Self>

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

type Archived = ArchivedSessionId

The archived representation of this type.

type Resolver = SessionIdResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve(&self, resolver: Self::Resolver, out: Place<Self::Archived>)

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for SessionId

fn clone(&self) -> SessionId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SessionId

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

Formats the value using the given formatter.

impl<__D: Fallible + ?Sized> Deserialize<SessionId, __D> for Archived<SessionId>

where u64: Archive, <u64 as Archive>::Archived: Deserialize<u64, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<SessionId, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl Hash for SessionId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SessionId

fn eq(&self, other: &SessionId) -> 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.

impl<__S: Fallible + ?Sized> Serialize<__S> for SessionId

where u64: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.
