reflectx

The sqlx package has special reflect needs. In particular, it needs to:

  • be able to map a name to a field
  • understand embedded structs
  • understand mapping names to fields by a particular tag
  • user specified name -> field mapping functions

These behaviors mimic the behaviors by the standard library marshallers and also the behavior of standard Go accessors.

The first two are amply taken care of by Reflect.Value.FieldByName, and the third is addressed by Reflect.Value.FieldByNameFunc, but these don't quite understand struct tags in the ways that are vital to most marshalers, and they are slow.

This reflectx package extends reflect to achieve these goals.
