#### go/types

The `Var.Kind` method returns an enumeration of type `VarKind` that
classifies the variable (package-level, local, receiver, parameter,
result, or struct field). See issue #70250.

Callers of `NewVar` or `NewParam` are encouraged to call `Var.SetKind`

## Forbid Extra Query Parameters { #forbid-extra-query-parameters }

In some special use cases (probably not very common), you might want to **restrict** the query parameters that you want to receive.

You can use Pydantic's model configuration to `forbid` any `extra` fields:
