Fieldname#- defining struct in racket -


assuming have following code in racket: 

(struct st ( field1 field2# ))

what # mean?

nothing, it's part of name field2#. racket allows symbols used in names. that's why you've got things hash-ref! , number? ordinary functions, despite having unusual symbols.

you can access , set other field:

(struct st (field1 field2#)) (define (st 1 2)) (st-field1 a) (st-field2# a)

this prints out

1 2

in drracket repl, expect of ordinary struct fields.
