cast

Overview

Description

Convert the base datatype of a data structure or datatype from one base type to another (i.e. [int32,int32] to [flat64,float64]). It is useful to note that maps of arrays are allowed and handle by the specification. Allowed types for toType: int64,float64,string,int32,float32,boolean.

Implementation details

The main data structure manipulation is done with relfect switch statements. But changing the base datatype is gone with the cast library used in Hugo: github.com/spf13/cast.
