error: `impl Sized` will capture more lifetimes than possibly intended in edition 2024
--> $DIR/overcaptures-2024-machine-applicable.rs:9:29
|
LL | fn named<'a>(x: &'a i32) -> impl Sized { *x }
| ^^^^^^^^^^
|
= warning: this changes meaning in Rust 2024
= note: for more information, see <https://doc.rust-lang.org/nightly/edition-guide/rust-2024/rpit-lifetime-capture.html>
note: specifically, this lifetime is in scope but not mentioned in the type's bounds
--> $DIR/overcaptures-2024-machine-applicable.rs:9:10
|
LL | fn named<'a>(x: &'a i32) -> impl Sized { *x }
| ^^
= note: all lifetimes in scope will be captured by `impl Trait`s in edition 2024
note: the lint level is defined here
--> $DIR/overcaptures-2024-machine-applicable.rs:7:9
|
LL | #![deny(impl_trait_overcaptures)]
| ^^^^^^^^^^^^^^^^^^^^^^^
help: use the precise capturing `use<...>` syntax to make the captures explicit
|
LL | fn named<'a>(x: &'a i32) -> impl Sized + use<> { *x }
