# sigs.k8s.io/json

[![Go Reference](https://pkg.go.dev/badge/sigs.k8s.io/json.svg)](https://pkg.go.dev/sigs.k8s.io/json)

## Introduction

This library is a subproject of [sig-api-machinery](https://github.com/kubernetes/community/tree/master/sig-api-machinery#json).
It provides case-sensitive, integer-preserving JSON unmarshaling functions based on `encoding/json` `Unmarshal()`.

## Compatibility

The `UnmarshalCaseSensitivePreserveInts()` function behaves like `encoding/json#Unmarshal()` with the following differences:

- JSON object keys are treated case-sensitively.
  Object keys must exactly match json tag names (for tagged struct fields)
  or struct field names (for untagged struct fields).
- JSON integers are unmarshaled into `interface{}` fields as an `int64` instead of a 
  `float64` when possible, falling back to `float64` on any parse or overflow error.
- Syntax errors do not return an `encoding/json` `*SyntaxError` error.
  Instead, they return an error which can be passed to `SyntaxErrorOffset()` to obtain an offset.

## Additional capabilities

The `UnmarshalStrict()` function decodes identically to `UnmarshalCaseSensitivePreserveInts()`,
and also returns non-fatal strict errors encountered while decoding:

- Duplicate fields encountered
- Unknown fields encountered
