Codegen panic with non-chrono DateTime

kjzl opened this issue · comments

commented

Describe the bug

The codegen tool experiences a panic when interacting with a DateTime type that is not from the chrono crate. This issue is specifically observed when using the exif::DateTime from the kamadak-exif crate. The tool appears to expect generics when dealing with a type named 'DateTime'.

Steps to reproduce

/// Works as expected
pub fn get_chrono_dt() -> chrono::DateTime<chrono::Utc> {
    chrono::DateTime::default()
}

/// Codegen panics
pub fn get_exif_dt() -> exif::DateTime {
    exif::DateTime::from_ascii(b"2016:05:04 03:02:01").unwrap()
}

Hi! Thanks for opening your first issue here! 😄

Yes, that looks like a bug. The problem is that, it is nontrivial to understand where a DateTime word comes from. For example:

  • use chrono::DateTime; fn f() -> DateTime {}
  • use exif::DateTime; fn f() -> DateTime {}
  • use x::Y as DateTime; fn f() -> DateTime {}
  • use chrono::*; fn f() -> DateTime {}
  • use exif::*; fn f() -> DateTime {}
  • use exif as chrono; fn f() -> chrono::DateTime {}
  • ...

However, for your specific case, it is reasonable to assume anything::DateTime is not a chrono datetime when anything != chrono. Feel free to PR, alternatively I will fix it in the next batch (hopefully within a week)!

A quick workaround before the real fix is that, use exif::DateTime as ExifDateTime to avoid name conflict.
