Struct RentCollectorWithMetrics

pub struct RentCollectorWithMetrics(/* private fields */);

Wrapper around RentCollector to allow for overriding of some SVMRentCollector trait methods, which are otherwise implemented on RentCollector directly.

Overrides inject logging and metrics submission into the rent state assessment process.
