Struct re_sdk::log::TableId

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

A unique ID for a DataTable.

Implementations

impl TableId

pub const ZERO: TableId = _

pub fn new() -> TableId

Create a new unique TableId based on the current time.

pub fn next(&self) -> TableId

Returns the next logical TableId.

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

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

Returns the n-next logical TableId.

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

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

Methods from Deref<Target = Tuid>

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.

pub const ZERO: Tuid = _

pub const MAX: Tuid = _

pub fn as_u128(&self) -> u128

pub fn nanoseconds_since_epoch(&self) -> u64

Approximate nanoseconds since unix epoch.

The upper 64 bits of the Tuid.

pub fn inc(&self) -> u64

The increment part of the Tuid.

The lower 64 bits of the Tuid.

pub fn next(&self) -> Tuid

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.

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

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.

pub fn short_string(&self) -> String

A shortened string representation of the Tuid.

impl Loggable for TableId

type Name = ComponentName

fn name() -> <TableId as Loggable>::Name
