#[async_trait] on SessionStore and ExpiredDeletion traits

[mispp]

Beginner here,

is there a reason why async_trait proc_macro is still used given that since 2023 async fn are allowed in trait objects?
Would this be possible to easily update?

Came to this while analyzing strongly-typed example.

It's needed for now due to object safety.

I haven't dug very deep, so I'm unclear if that's a limitation that will likely always exist or not.

[mispp]

Not sure if this helps.

Basically it says there are two reasons why to still use async_trait macro:

• You want to support Rust versions older than 1.75.
• You want dynamic dispatch.

Also

As stated above, we hope to enable dynamic dispatch in a future version of the trait-variant crate.

Since im a beginner, this doesnt mean much to me.

[maxcountryman]

Relative to this crate, it means async_trait is still required.
