The "cannot create non-exhaustive struct using struct expression" warning should silence the "cannot construct Foo with struct literal syntax due to private fields" warning #147513
Description
Code
// src/lib.rs
#[non_exhaustive]
pub struct Foo {
pub my_field: u32,
private_field: i32,
}// src/main.rs
use exhaustive_test::Foo;
fn main() {
let foo = Foo {
my_field: 10,
};
}Current output
error[E0639]: cannot create non-exhaustive struct using struct expression
--> src/main.rs:4:15
|
4 | let foo = Foo {
| _______________^
5 | | my_field: 10,
6 | | };
| |_____^
error: cannot construct `Foo` with struct literal syntax due to private fields
--> src/main.rs:4:15
|
4 | let foo = Foo {
| ^^^
|
= note: ...and other private field `private_field` that was not provided
Desired output
error[E0639]: cannot create non-exhaustive struct using struct expression
--> src/main.rs:4:15
|
4 | let foo = Foo {
| _______________^
5 | | my_field: 10,
6 | | };
| |_____^
Rationale and extra context
There is no reason to provide two errors for the same issue, and the #[non_exhaustive] issue is the one that should be highlighted since it's explicitly chosen by the struct author.
Other cases
If there is no private field, then the correct output is created.
