Struct Tuid

Source 
pub struct Tuid { /* private fields */ }

Implementations§

Source§

impl Tuid

Source

pub fn heap_size_bytes(&self) -> u64

Returns the total size of self on the heap, in bytes.

NOTE: This crate cannot depend on re_types_core, therefore the actual implementation of SizeBytes for Tuid lives in re_types_core and calls this method.

Source§

impl Tuid

Source

pub const ZERO: Self = _

All zeroes.

Source

pub const MAX: Self = _

All ones.

Source

pub fn new() -> Self

Create a new unique Tuid based on the current time.

Source

pub fn from_nanos_and_inc(time_ns: u64, inc: u64) -> Self

Construct a Tuid from the upper and lower halves of a u128-bit. The first should be nano-seconds since epoch.

Source

pub fn from_u128(id: u128) -> Self

Source

pub fn as_u128(&self) -> u128

Source

pub fn nanoseconds_since_epoch(&self) -> u64

Approximate nanoseconds since unix epoch.

The upper 64 bits of the Tuid.

Source

pub fn inc(&self) -> u64

The increment part of the Tuid.

The lower 64 bits of the Tuid.

Source

pub fn next(&self) -> Self

Returns the next logical Tuid.

Wraps the monotonically increasing back to zero on overflow.

Beware: wrong usage can easily lead to conflicts. Prefer Tuid::new when unsure.

Source

pub fn incremented_by(&self, n: u64) -> Self

Returns the n-next logical Tuid.

This is equivalent to calling Tuid::next n times. Wraps the monotonically increasing back to zero on overflow.

Beware: wrong usage can easily lead to conflicts. Prefer Tuid::new when unsure.

Source

pub fn short_string(&self) -> String

A shortened string representation of the Tuid.
