Struct RecordId 

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

Monotonically-increasing identifier for an audit record.

Ids start at 0 for the genesis record and increment by one for every successful append.

Example

use audit_trail::RecordId;

let id = RecordId::from_u64(7);
assert_eq!(id.as_u64(), 7);

Implementations

impl RecordId

pub const GENESIS: Self

The first identifier produced by a fresh chain.

pub const fn from_u64(value: u64) -> Self

Wrap a raw u64 as a RecordId.

pub const fn as_u64(self) -> u64

Return the underlying u64.

Trait Implementations

impl Clone for RecordId

fn clone(&self) -> RecordId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RecordId

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

Formats the value using the given formatter.

impl Default for RecordId

fn default() -> RecordId

Returns the “default value” for a type.

impl Hash for RecordId

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 RecordId

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

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

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