Not compiling

[guimath]

Hi i was trying to compile another lib using rosrust when it failed. I first tried to understand the issue so i cloned this repo and tried a local build directly. Still, it fails...

Here is of the errors:

error[E0308]: mismatched types
   --> rosrust/src/api/ros.rs:71:79
    |
71  |                 .subscribe::<ClockMsg, _>("/clock", 1, move |v| clock.trigger(v.clock))
    |                                                                       ------- ^^^^^^^ expected `time::Time`, found `builtin_interfaces::Time`
    |                                                                       |
    |                                                                       arguments to this method are incorrect
    |
    = note: `builtin_interfaces::Time` and `time::Time` have similar names, but are actually distinct types

Also some problems in the rosrust/src/msg.rs, with the macro expanded:

error[E0609]: no field `seq` on type `Header`
  --> rosrust/src/msg.rs:87:28
   |
87 |             if self.header.seq == 0 {
   |                            ^^^ unknown field
   |
   = note: available fields are: `stamp`, `frame_id`

I am using rustc 1.81.0 (on Linux Mint 21.1 Cinnamon) and don't really understand what's going on here. I am fully assuming that the problem is linked to my machine but don't really know where to look, any idea ?

Hello , @guimath , As far as I understood from first error error[E0308]: mismatched types --> rosrust/src/api/ros.rs:71:79 | 71 | .subscribe::<ClockMsg, _>("/clock", 1, move |v| clock.trigger(v.clock)) | ------- ^^^^^^^ expected time::Time, found builtin_interfaces::Time| | | arguments to this method are incorrect | = note:builtin_interfaces::Timeandtime::Timehave similar names, but are actually distinct types

clock.trigger takes an argument of type time::Time` but got builtin_interfaces::Time``

The second error is saying your header does not have a function seq other , other fields are stamp, frame_id

can you please elaborate on how to replicate this error

This is after no change to the code, simply running build on the freshly cloned repo.

For the second error it shows also without any changes but i just expand the macro to get a better understanding. I understand the errors (although have dived too much in the code and so don't know what to change), what I don't get is how I am apparently the only one for who it is not working (I haven't tried it on another PC but I assume a published crate should be generally working)
