Trait TimeKey

Source
pub trait TimeKey: Copy {
    // Required methods
    fn timestamp_us(&self) -> u64;
    fn partition(&self) -> u64;

    // Provided method
    fn key(&self) -> TimeKeyItem { ... }

Expand description

TimeKey is a trait that defines the interface for a time key.

A stream set will be

  • ordered on timestamp
  • columnar on partition
  • compressed at rest
  • backed by a u128 value

Required Methods§

Source

fn timestamp_us(&self) -> u64

Source

fn partition(&self) -> u64

Provided Methods§

Source

fn key(&self) -> TimeKeyItem

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors§

impl TimeKey for UserDeviceTimeKey

Implement the TimeKey trait for UserDeviceTimeKey so that it can be used in a TkStreamSet.
