FastReflect

(English / 中文)

A faster method to get elements from an interface (Struct or Slice type) for Go.

Usage

import (
    "github.com/karminski/fastreflect"
)

// Access an interface (struct type) property by name
TheFieldYouWant := fastreflect.StructFieldByName(YourStructInterface, "FieldName")

// Get all elements from an interface (slice type)
AllElementsYouWant := fastreflect.SliceAllElements(YourSliceInterface)

For more details please see: FastReflect_test.go

Performance

  • Access an interface (struct type) property by name, 3.58x fast.
  • Get all elements from an interface (slice type), 4.3x fast.
