Legend:

  • ✗ means using this operator with a value type of this kind will always fail
  • ✓ means using this operator with a value type of this kind can succeed
  • []byte, time.Time, ptr on X, fmt.Stringer, error means using this operator with this go type can succeed
  • todo means should be implemented in future (PRs welcome :) )
  • ¹ + ✓ means using this operator with the data behind the interface can succeed

go type → operator matrix

Operators likely to succeed for each go type:

Untyped nil value

bool values (or any type based on bool)

string values (or any type based on string)

Integer values (uint*, int* or any type based on them)

Float values (float32, float64 or any type based on them)

Complex values (complex64, complex128 or any type based on them)

Arrays

Slices

Maps

Structs

Interface values

As all operators accept interface values, only specific interfaces are listed below:

Any pointer

Channels

Functions
