A tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Are you sure you want to create this branch?

Go Reference

Introduction

This library is a subproject of sig-api-machinery. 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
