Struct Ulid 

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

A ULID — 26-char Crockford base32, lexicographically sortable by time.

Implementations

impl Ulid

pub fn generate() -> Self

Generate a new ULID using the current timestamp and random bits.

pub fn monotonic() -> Self

Generate a monotonically increasing ULID: within the same millisecond the random component is incremented instead of re-randomised.

pub fn as_str(&self) -> &str

pub fn timestamp_ms(&self) -> u64

Extract the timestamp component in milliseconds.

Trait Implementations

impl AsRef<str> for Ulid

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Ulid

fn clone(&self) -> Ulid

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Ulid

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Ulid

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Ulid

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

Formats the value using the given formatter.

impl FromStr for Ulid

type Err = IdError

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 Ulid

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 Ulid

fn eq(&self, other: &Ulid) -> 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 Serialize for Ulid

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
