Struct NetId64 

pub struct NetId64(pub u64);

Runtime-bound 64-bit identifier with [KIND:8][NODE:16][COUNTER:40] layout.

Copy + Clone + PartialEq + Eq + Hash + Ord — small value, identity-by-bits, usable as a map key.

Tuple Fields

0: u64

Implementations

impl NetId64

pub const ZERO: NetId64

The all-zeros id. Useful as a sentinel; not a valid mint.

pub const fn from_raw(value: u64) -> NetId64

Construct from raw u64.

pub const fn raw(self) -> u64

The raw u64 representation.

pub const fn kind(self) -> u8

The KIND byte — which type this id refers to.

pub const fn node(self) -> u16

The NODE part — which node, shard, partition, or runtime minted this id.

pub const fn counter(self) -> u64

The COUNTER part — caller-defined local sequence value.

pub const fn make(kind: u8, node: u16, counter: u64) -> NetId64

Build an id from the three fields. The counter is truncated to 40 bits.

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

Big-endian wire bytes.

pub const fn from_be_bytes(bytes: [u8; 8]) -> NetId64

Reconstruct from big-endian wire bytes.

Trait Implementations

impl Clone for NetId64

fn clone(&self) -> NetId64

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NetId64

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

Debug shows both the triple and the raw hex — handy in logs.

impl Display for NetId64

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

Canonical decimal form: "kind:node:counter".

impl FromStr for NetId64

fn from_str(s: &str) -> Result<NetId64, <NetId64 as FromStr>::Err>

Accepts both forms:

• "7:42:999" — decimal triple
• "0xDEADBEEF..." — raw hex u64

type Err = ParseNetId64Error

The associated error which can be returned from parsing.

impl Hash for NetId64

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

where __H: Hasher,

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 Ord for NetId64

fn cmp(&self, other: &NetId64) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for NetId64

fn eq(&self, other: &NetId64) -> 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 PartialOrd for NetId64

fn partial_cmp(&self, other: &NetId64) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
