= warning: this is accepted in the current edition (Rust 2015) but is a hard error in Rust 2021!
|
|
= note: for more information, see <https://doc.rust-lang.org/nightly/edition-guide/rust-2021/warnings-promoted-to-error.html>

= note: `--force-warn bare-trait-objects` implied by `--force-warn rust-2018-idioms`
|
|
= help: to override `--force-warn rust-2018-idioms` add `#[allow(bare_trait_objects)]`
|
|
help: if this is an object-safe trait, use `dyn`
