Struct bones_lib::ecs::prelude::CurrentSystemStage

pub struct CurrentSystemStage(pub Ulid);

Resource that is automatically added to the world while a system stage is being run that specifies the unique ID of the stage that being run.

If the stage is Ulid(0), the default ID, then that means the startup stage is being run.

Tuple Fields

0: Ulid

Methods from Deref<Target = Ulid>

pub fn datetime(&self) -> SystemTime

Gets the datetime of when this Ulid was created accurate to 1ms

Example

use std::time::{SystemTime, Duration};
use ulid::Ulid;

let dt = SystemTime::now();
let ulid = Ulid::from_datetime(dt);

assert!(
    dt + Duration::from_millis(1) >= ulid.datetime()
    && dt - Duration::from_millis(1) <= ulid.datetime()
);

pub const TIME_BITS: u8 = 48u8

pub const RAND_BITS: u8 = 80u8

pub fn timestamp_ms(&self) -> u64

Gets the timestamp section of this ulid

Example

use std::time::{SystemTime, Duration};
use ulid::Ulid;

let dt = SystemTime::now();
let ulid = Ulid::from_datetime(dt);

assert_eq!(u128::from(ulid.timestamp_ms()), dt.duration_since(SystemTime::UNIX_EPOCH).unwrap_or(Duration::ZERO).as_millis());

pub fn random(&self) -> u128

Gets the random section of this ulid

Example

use ulid::Ulid;

let text = "01D39ZY06FGSCTVN4T2V9PKHFZ";
let ulid = Ulid::from_string(text).unwrap();
let ulid_next = ulid.increment().unwrap();

assert_eq!(ulid.random() + 1, ulid_next.random());

pub fn to_str<'buf>( &self, buf: &'buf mut [u8], ) -> Result<&'buf mut str, EncodeError>

👎Deprecated since 1.2.0: Use the infallible array_to_str instead.

Creates a Crockford Base32 encoded string that represents this Ulid

Example

use ulid::Ulid;

let text = "01D39ZY06FGSCTVN4T2V9PKHFZ";
let ulid = Ulid::from_string(text).unwrap();

let mut buf = [0; ulid::ULID_LEN];
let new_text = ulid.to_str(&mut buf).unwrap();

assert_eq!(new_text, text);

pub fn array_to_str<'buf>(&self, buf: &'buf mut [u8; 26]) -> &'buf mut str

Creates a Crockford Base32 encoded string that represents this Ulid

Example

use ulid::Ulid;

let text = "01D39ZY06FGSCTVN4T2V9PKHFZ";
let ulid = Ulid::from_string(text).unwrap();

let mut buf = [0; ulid::ULID_LEN];
let new_text = ulid.array_to_str(&mut buf);

assert_eq!(new_text, text);

pub fn to_string(&self) -> String

Creates a Crockford Base32 encoded string that represents this Ulid

Example

use ulid::Ulid;

let text = "01D39ZY06FGSCTVN4T2V9PKHFZ";
let ulid = Ulid::from_string(text).unwrap();

assert_eq!(&ulid.to_string(), text);

pub fn is_nil(&self) -> bool

Test if the Ulid is nil

Example

use ulid::Ulid;

let ulid = Ulid::new();
assert!(!ulid.is_nil());

let nil = Ulid::nil();
assert!(nil.is_nil());

pub fn increment(&self) -> Option<Ulid>

Increment the random number, make sure that the ts millis stays the same

pub fn to_bytes(&self) -> [u8; 16]

Returns the bytes of the Ulid in big-endian order.

Example

use ulid::Ulid;

let text = "7ZZZZZZZZZZZZZZZZZZZZZZZZZ";
let ulid = Ulid::from_string(text).unwrap();

assert_eq!(ulid.to_bytes(), [0xFF; 16]);
