## What it is
A .NET library that generates 64-bit, roughly time-ordered unique IDs inspired by Twitter's Snowflake. It lets you customize the bit layout of timestamp, generator-id, and sequence parts, but does not provide worker-id coordination services.

## Use cases
- generate unique ids in a distributed .net system
- snowflake-style id generator for c#
- low-latency time-ordered id generation
- generate compact 64-bit unique identifiers
- uncoordinated id generation across multiple hosts
- custom bit layout for id generator timestamp and sequence

## When to choose
- you need low-latency, roughly time-ordered unique IDs in a .NET application
- you can assign unique generator-ids to each host or thread yourself
- you want a customizable bit structure for timestamp, generator-id, and sequence

## When to avoid
- you need a service that coordinates worker-ids across nodes automatically
- you need globally coordinated or strictly ordered IDs
- you are not on the .NET platform

## Facets
- artifact type: library
- maturity: stable
- function: sdk, developer-tools
- domain: databases, microservices, developer-tools
- platform: dotnet, cross-platform
- tags: snowflake, id-generation, unique-ids, c-sharp, distributed-systems
