Christian Haudum	d8cc1cea83	chore: Make dedicated iterator package (#13273) ... Iterators of various types are widely used throughout the Loki code base. With the recent code additions of the bloom filters, a new set of utility functions for iterators emerged in `github.com/grafana/loki/v3/pkg/storage/bloom/v1`. The package defines interfaces for various common types, but also provides implementations to create and compose new iterators that implement these interfaces. This new package uses Go Generics. - However, at the current state, there are multiple iterator interfaces and implementations, which adds cognitive overhead in understanding how they work and which ones should be used. The idea is to unify them into a single iterator lib for Loki. - As a first step towards a single iterator library for the Loki code base, this PR moves the utilities from the `pkg/storage/bloom/v1` package to the `pkg/iter/v2` package. - Second, it changes the existing `EntryIterator` and `SampleIterator` iterators to "inherit" `v2.CloseIterator` in order to expose the same function names. - And lastly, naming conventions of iterator interfaces and structs are unified. The basic iterator interface (defined in `pkg/iter/v2/interface.go`) looks like so: ```go // Usage: // // for it.Next() { // curr := it.At() // // do something // } // if it.Err() != nil { // // do something // } type Iterator[T any] interface { Next() bool Err() error At() T } ``` --- Signed-off-by: Christian Haudum <christian.haudum@gmail.com>	2 years ago
