@mzlib[#:mode title unit]

The @racketmodname[mzlib/unit] library mostly re-provides
@racketmodname[racket/unit], except for @racket-struct and
@racket-struct/ctc from @racketmodname[racket/unit].

@defform/subs[(struct id (field-id ...) omit-decl ...)
              ([omit-decl -type
                          -selectors
                          -setters
                          -constructor])]{

A signature form like @racket-struct from @racketmodname[racket/unit],
but with a different syntax for the options that limit exports.}

@defform/subs[(struct/ctc id ([field-id contract-expr] ...) omit-decl ...)
              ([omit-decl -type
                          -selectors
                          -setters
                          -constructor])]{

A signature form like @racket-struct/ctc from @racketmodname[racket/unit],
but with a different syntax for the options that limit exports.}

@deftogether[(
@defidform[struct~s]
@defidform[struct~s/ctc]
)]{

The same as @|racket-struct| and @|racket-struct/ctc| from
@racketmodname[racket/unit].}

@deftogether[(
@defidform[struct~r]
@defidform[struct~r/ctc]
)]{

Like @racket[struct~s] and @racket[struct~s/ctc], but the constructor is
named the same as the type, instead of with  @racketidfont{make-} prefix.}
