Benchmark

Bench To Generate Fake Data

Without Tag

BenchmarkFakerDataNOTTagged-4             500000              3049 ns/op             488 B/op         20 allocs/op

Using Tag

 BenchmarkFakerDataTagged-4                100000             17470 ns/op             380 B/op         26 allocs/op

MUST KNOW

The Struct Field must PUBLIC.
Support Only For :

  • int int8 int16 int32 int64
  • []int []int8 []int16 []int32 []int64
  • bool []bool
  • string []string
  • float32 float64 []float32 []float64
  • Nested Struct Field
  • time.Time []time.Time

Limitation

Unfortunately this library has some limitation

  • It does not support private fields. Make sure your structs fields you intend to generate fake data for are public, it would otherwise trigger a panic. You can however omit fields using a tag skip faker:"-" on your private fields.
  • It does not support the interface{} data type. How could we generate anything without knowing its data type?
  • It does not support the map[interface{}]interface{}, map[any_type]interface{}, map[interface{}]any_type data types. Once again, we cannot generate values for an unknown data type.
  • Custom types are not fully supported. However some custom types are already supported: we are still investigating how to do this the correct way. For now, if you use faker, it's safer not to use any custom types in order to avoid panics.
