Enum TnidVariant 

pub enum TnidVariant {
    V0,
    V1,
    V2,
    V3,
}

The 4 possible TNID variants.

Similar to UUID variants, TNID variants have different construction that makes them useful for different situations.

Variants

V0

V0 is most like UUIDv7, and is meant to be time-sortable. See Tnid::new_v0.

V1

V1 is most like UUIDv4, and is meant to maximize entropy (randomness). See Tnid::new_v1.

V2

V2 is undefined but reserved for future use.

V3

V3 is undefined but reserved for future use.

Implementations

impl TnidVariant

pub fn from_u8(variant_bits: u8) -> TnidVariant

Converts a u8 to a TnidVariant.

Only the bottom 2 bits are used to determine the variant (ignores the top 6 bits). For example, 0b0000_0000, 0b0000_0100, and 0b1111_1100 all have bottom 2 bits of 00, so they all map to V0.

Examples

use tnid::TnidVariant;

// Bottom 2 bits are 0b00 -> V0
assert_eq!(TnidVariant::from_u8(0b00000000), TnidVariant::V0);
assert_eq!(TnidVariant::from_u8(0b11111100), TnidVariant::V0);

// Bottom 2 bits are 0b01 -> V1
assert_eq!(TnidVariant::from_u8(0b00000001), TnidVariant::V1);
assert_eq!(TnidVariant::from_u8(0b11111101), TnidVariant::V1);

pub fn as_u8(&self) -> u8

Returns the u8 representation of this variant.

Examples

use tnid::TnidVariant;

assert_eq!(TnidVariant::V0.as_u8(), 0);
assert_eq!(TnidVariant::V1.as_u8(), 1);
assert_eq!(TnidVariant::V2.as_u8(), 2);
assert_eq!(TnidVariant::V3.as_u8(), 3);

Trait Implementations

impl Debug for TnidVariant

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

Formats the value using the given formatter.

impl PartialEq for TnidVariant

fn eq(&self, other: &TnidVariant) -> 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.
