Types

type IntValueDecoder

type IntValueDecoder[T inty] struct {
	// contains filtered or unexported fields
}

IntValueDecoder is a type wrapping an int pointer so it can decode integer values from Spanner directly (Spanner prefers to work only in int64s).

func Int

func Int[T inty](val *T) IntValueDecoder[T]

Int wraps a pointer to an int-based type in a type that can be decoded directly from Spanner.

In general, it is preferable to add EncodeSpanner/DecodeSpanner methods to our specialized int types, but this can be used for types we don't own or otherwise can't put methods on.

func (IntValueDecoder[T]) DecodeSpanner

func (s IntValueDecoder[T]) DecodeSpanner(input any) error

DecodeSpanner decodes a value from a Spanner-stored type to the appropriate int type. It implements spanner.Decoder.
