Struct ObjectId 

pub struct ObjectId { /* private fields */ }

A unique identifier for an object being encoded/decoded.

Objects are the high-level data units that get split into symbols for erasure-coded transmission. Each object has a unique 128-bit ID.

Implementations

impl ObjectId

pub const NIL: Self

The nil (zero) object ID.

pub const fn new(high: u64, low: u64) -> Self

Creates a new object ID from two 64-bit values.

pub const fn from_u128(value: u128) -> Self

Creates an object ID from a 128-bit value.

pub const fn as_u128(self) -> u128

Converts the object ID to a 128-bit value.

pub const fn high(self) -> u64

Returns the high 64 bits.

pub const fn low(self) -> u64

Returns the low 64 bits.

pub fn new_random(rng: &mut DetRng) -> Self

Creates a random object ID using a deterministic RNG.

This is the primary way to create object IDs in production code.

Trait Implementations

impl Clone for ObjectId

fn clone(&self) -> ObjectId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ObjectId

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

Formats the value using the given formatter.

impl Display for ObjectId

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

Formats the value using the given formatter.

impl Hash for ObjectId

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 Ord for ObjectId

fn cmp(&self, other: &ObjectId) -> 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 ObjectId

fn eq(&self, other: &ObjectId) -> 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 ObjectId

fn partial_cmp(&self, other: &ObjectId) -> 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.
