Consider this setup:

// crate A

struct Example { field1: u8, field2: u8 }

impl Example {
  fn use_lib() { ... }
}

// crate B

use crateA::Example;

Crate B uses a struct from crate A that has an associated function that uses a few crate A dependencies. These crate A dependencies that needed in crate B (only the struct is needed). Is there a way import the struct from crate A in crate B without importing all the dependencies of crate A?

Solutions I'm considering:

• Move struct into crate C, create a wrapper in crate A and implement the functions on the wrapper
• Create a macro that copies the struct (without the associated functions) from crate A into crate B. A bit harder if the struct depends on other structs defined in crate A.

Curious to hear other Ideas or thoughts
