Ignoring certain columns of file with serde #58

Closed texasfight closed 1 year ago

texasfight commented 1 year ago

I have some .dbf files that contain a lot of junk columns from a POS system and am trying to figure out the best way to ignore those columns. If I put just the names of the columns I want, it ends up just renaming the first n columns to those names rather than plucking out those columns. Is there a way to only get the columns I want using serde rather than having to define data types for all of the columns I don't want (100+)?

Example:

File columns:

  1. a
  2. b
  3. c
  4. d

What I want:

  1. a
  2. c

Thank you in advance for your help.

This is not possible, and would probably require changes to the serde implementation

The better option would be to implement your own convertion form a dbase::Record to your struct

Got it, that was my backup plan. Thanks for your help!
