Struct ExecutionID

pub struct ExecutionID {
    pub id: [u8; 16],
}

A one_two_eight identifier.

Fields

id: [u8; 16]

The raw bytes for this identifier.

Implementations

impl ExecutionID

pub const BOTTOM: ExecutionID

The smallest identifier.

pub const TOP: ExecutionID

The largest identifier.

pub fn generate() -> Option<ExecutionID>

Generate a new identifier, failing if urandom fails.

pub fn from_human_readable(s: &str) -> Option<Self>

Construct an identifier from its human-readable form.

pub fn human_readable(&self) -> String

Construct a string corresponding to the human-readable form of this identifier.

pub fn prefix_free_readable(&self) -> String

Return the prefix-free encoding of this identifier.

pub fn new(id: [u8; 16]) -> Self

Create a new identifier from raw bytes.

pub fn next(self) -> Self

Increment the identifier by one.

Trait Implementations

impl Clone for ExecutionID

fn clone(&self) -> ExecutionID

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExecutionID

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

Formats the value using the given formatter.

impl Default for ExecutionID

fn default() -> ExecutionID

Returns the “default value” for a type.

impl Display for ExecutionID

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

Formats the value using the given formatter.

impl FromStr for ExecutionID

type Err = &'static str

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for ExecutionID

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 ExecutionID

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

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

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