about import warning

[lydiandy]

V version: latest:V 0.1.25 5a6f4aa OS: mac

What did you do? in my module,when I import time module,I just want to use the C function defined

pub struct C.timeval {
	tv_sec  u64
	tv_usec u64
}

I do not use any other function or struct in time module

What did you expect to see? the code can run without a warning. I think one module just only use the C function defined in the other module,It can also be treated as use the module

What did you see instead? the V compiler give me a warning:the following imports were never used: time so I have to redefine C.timeval struct in my own module

tiny replication:

module main

pub struct C.aa {
	a  u64
}

pub fn main() {}

just use:

import time as _

to avoid th warning.

looks like v does not see the c struct as belonging to time anyway as you can use it without the time. prefix.

$ v run x.v
x.v:3:8: warning: module 'time' is imported but never used. Use `import time as _`, to silence this warning, or just remove the unused import line
