A .NET library for generating Time-Sorted Unique Identifiers (TSID). Compatible with .NET Standard 2.0/.NET Standard 2.1.

It brings together ideas from Twitter's Snowflake and ULID Spec.

In summary:

• Sorted by generation time;
• Can be stored as an integer of 64 bits;
• Can be stored as a string of 13 chars;
• String format is encoded to Crockford's base32;
• String format is URL safe, is case insensitive, and has no hyphens;
• Shorter than UUID, ULID and KSUID.

This library is a port of the Java code found here.

It is highly recommended to consult first the original Java code before using this library, in terms of usage and performance.

Create a TSID:

Tsid tsid = TsidCreator.GetTsid();

Create a TSID as long:

long number = TsidCreator.GetTsid().ToLong(); // 38352658567418872

Create a TSID as String:

string string = TsidCreator.GetTsid().ToString(); // 01226N0640J7Q

The TSID generator is thread-safe.
