I tried this code from https://github.com/rust-lang/rust/blob/master/tests/ui/associated-types/issue-20005.rs
test.rs
trait From<Src> {
type Result;
fn from(src: Src) -> Self::Result;
}
trait To {
fn to<Dst>(
self //~ ERROR the size for values of type
) -> <Dst as From<Self>>::Result where Dst: From<Self> { //~ ERROR the size for values of type
From::from(self) //~ ERROR the size for values of type
}
}
fn main() {}
test.stderr

error: aborting due to 3 previous errors
For more information about this error, try `rustc --explain E0277`.
Expected behavior:
trait From<Src> {
type Result;
fn from(src: Src) -> Self::Result;
}
trait To {
fn to<Dst>(
self // { dg-error ".E0277." "" { target *-*-* } }
) -> <Dst as From<Self>>::Result where Dst: From<Self> { // { dg-error ".E0277." "" { target *-*-* } }
From::from(self) // { dg-error ".E0277." "" { target *-*-* } }
}
}
fn main() {}
Actual behavior:
- No error codes
trait From<Src> {
type Result;
fn from(src: Src) -> Self::Result;
}
trait To {
fn to<Dst>(
self // { dg-error "" "" { target *-*-* } }
) -> <Dst as From<Self>>::Result where Dst: From<Self> { // { dg-error "" "" { target *-*-* } }
From::from(self) // { dg-error "" "" { target *-*-* } }
}
}
fn main() {}

This is a simple bug, we just have to remove this line: https://github.com/MahadMuhammad/rusttest-to-dg/blob/8e33173c353f0c1fe27436999433548e6b599e63/src/errors.rs#L131
