how to avoid a password field in toString

[si chen]

Hi
I am using thrift to pass a struct like below:

struct User {
1: string user;
2: string password;
}

It works as expected, however, the "toString" method generated by thrift
always add the password field in plain text, how can I instruct thrift NOT
to include password field in toString method? I mean, if I log the struct, I
don't want to see the password being printed to log in plain text.

User u;
u.setUser("user");
u.setPassword("1234");
log.info(u);

Thanks
Si
