pub type Evictor<'i> = dyn FnMut() -> Result<(), AutotuneError> + Send + 'i;Expand description
An Eviction bound to one key and the reference inputs of one tune: what a benchmark
loop calls before each sample.
FnMut rather than Fn because the loop lends it out exclusively: the closure holds the
inputs, which are only Send, and a shared borrow would need them Sync to reach the
device thread the samples are launched from.
