data

Some utilities for handling data in Go.

  • object.go - a map that preserves key order during JSON round trip
  • decimal.go - a wrapper for math/big.Float that marshals to/from JSON
  • timestamp.go - a wrapper for time.Time that marshals to/from JSON as RFC 3339 text.
  • misc.go - some miscellaneous helpers
