Implementations

impl Qtid

pub fn random() -> Self

Available on crate feature rand only.

Generate a new random Qtid.

This method generate a cryptgraphicaly random ID. The generated ID is guaranteed to not be the NIL value.

Examples

let id = Qtid::random();
assert_ne!(id, Qtid::NIL);

impl Qtid

pub const BITS: u32 = 60u32

The size of the integer type in bits. This is not equal actually stored size.

pub const CAPACITY: u64 = 1_152_921_504_606_846_976u64

The capacity value of this triplet id type

#Examples

assert_eq!(Qtid::MAX, Qtid::CAPACITY -1);

pub const NIL: Self

The smallest value that can be represented by this triplet id type.

Examples

assert_eq!(Qtid::NIL, "000-000-000-000".parse::<Qtid>()?);
assert_eq!(Qtid::NIL, Qtid::try_from(0)?);

pub const MAX: Self

The largest value that can be represent by this triplet id type.

Examples

assert_eq!(Qtid::MAX, "zzz-zzz-zzz-zzz".parse::<Qtid>()?);
assert_eq!(Qtid::MAX, Qtid::try_from(1152921504606846975)?);

pub fn is_nil(self) -> bool

Test if the triplet id is nil.

Examples

assert!("000-000-000-000".parse::<Qtid>()?.is_nil());

pub fn is_max(self) -> bool

Test if the triplet id is max.

Examples

assert!("zzz-zzz-zzz-zzz".parse::<Qtid>()?.is_max());

pub fn from_int_lossy(int: u64) -> Self

Convert from uint. If the value is equal Self::Capacity or more, the higher bits will be lost.

Examples

assert!(Qtid::from_int_lossy(Qtid::CAPACITY - 1).is_max());
assert!(Qtid::from_int_lossy(Qtid::CAPACITY).is_nil());
