This package exposes a registry of data types to support string formats in the go-openapi toolkit.

strfmt represents a well known string format such as credit card or email. The go toolkit for OpenAPI specifications knows how to deal with those.

## Supported data formats
go-openapi/strfmt follows the swagger 2.0 specification with the following formats
defined [here](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/2.0.md#data-types).

It also provides convenient extensions to go-openapi users.

- [x] JSON-schema draft 4 formats
  - date-time
  - email
  - hostname
  - ipv4
  - ipv6
  - uri
- [x] swagger 2.0 format extensions
  - binary
  - byte (e.g. base64 encoded string)
  - date (e.g. "1970-01-01")
  - password
- [x] go-openapi custom format extensions
  - bsonobjectid (BSON objectID)
  - creditcard
  - duration (e.g. "3 weeks", "1ms")
  - hexcolor (e.g. "#FFFFFF")
  - isbn, isbn10, isbn13
  - mac (e.g "01:02:03:04:05:06")
  - rgbcolor (e.g. "rgb(100,100,100)")
  - ssn
  - uuid, uuid3, uuid4, uuid5
  - cidr (e.g. "192.0.2.1/24", "2001:db8:a0b:12f0::1/32")

> NOTE: as the name stands for, this package is intended to support string formatting only.
> It does not provide validation for numerical values with swagger format extension for JSON types "number" or
> "integer" (e.g. float, double, int32...).
