how can i remove or reduce the amount of reflect

[shigetaichi]

package reflect can affect the performance. So i'd like to look for some way of remove or reduce this package.

apparently, "interface" of go make programs slow. reflect package use interface, so it will be slow.

how can i remove or reduce.

When there is the concept of "From struct, to csv", maybe i have to use reflect package.
Because it is necessary that to retrieve struct field data to generate record of csv.
is there any fast and easy way to get those data without "struct tag"?
