**A parser for URNs**.
|
|
|
|
> As seen on [RFC 2141](https://datatracker.ietf.org/doc/html/rfc2141), [RFC 7643](https://datatracker.ietf.org/doc/html/rfc7643#section-10), and on [RFC 8141](https://datatracker.ietf.org/doc/html/rfc8141).
|
|
|
|
[API documentation](https://godoc.org/github.com/leodido/go-urn).
|
|
|
|
Starting with version 1.3 this library also supports [RFC 7643 SCIM URNs](https://datatracker.ietf.org/doc/html/rfc7643#section-10).
|
|
|
|
Starting with version 1.4 this library also supports [RFC 8141 URNs (2017)](https://datatracker.ietf.org/doc/html/rfc8141).
|
|
|
|
## Installation
|
|
|
|
```
|
|
go get github.com/leodido/go-urn
|
|
```
|
|
|
|
## Features
|
|
|
|
1. RFC 2141 URNs parsing (default)
|
|
2. RFC 8141 URNs parsing (supersedes RFC 2141)
|
|
3. RFC 7643 SCIM URNs parsing
|
|
4. Normalization as per RFCs
|
|
5. Lexical equivalence as per RFCs
|
|
6. Precise, fine-grained errors
|
|
|
|
## Performances
|
|
|
|
This implementation results to be really fast.
|
|
|
|
Usually below 400 ns on my machine<sup>[1](#mymachine)</sup>.
|
|
|
|
Notice it also performs, while parsing:
|
|
|
|
1. fine-grained and informative erroring
|
|
2. specific-string normalization
