Trait TuneInputs 

pub trait TuneInputs:
    Send
    + Sync
    + 'static {
    type At<'a>: Clone + Send;
}

Describes the set of inputs a TunableSet accepts.

The associated type At gives the concrete input type at a specific lifetime. The indirection exists because TunableSet must be 'static (to live in LocalTuner’s Arc<dyn Any> cache), but some callers want to pass borrowed inputs. A 'static marker type with a lifetime-parameterized works here: the set is 'static, but every tunable function accepts Self::At<'a> for any 'a via HRTB.

Implementing it manually is needed when the inputs genuinely borrowed. Example: burn’s fusion autotune passes TuneInput<'a, R, O> (which wraps &'a mut Context) by defining a FusionTuneInputs<R, O> marker with At<'a> = TuneInput<'a, R, O>. Such a marker must not implement Clone, otherwise it would overlap with the blanket impl below.

Required Associated Types

type At<'a>: Clone + Send

The concrete input type at lifetime 'a.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
