Streaming statistics accumulator using Welford's algorithm and TDigest.

## Structs

* [AccumulatorState](/reference/api/rust-library-reference/nemo-relay-adaptive/trie/accumulator/struct-accumulatorstate): Maps trie path strings to their node accumulators.
* [NodeAccumulators](/reference/api/rust-library-reference/nemo-relay-adaptive/trie/accumulator/struct-nodeaccumulators): Per-node accumulators for all metric types, keyed by call index.
* [RunningStats](/reference/api/rust-library-reference/nemo-relay-adaptive/trie/accumulator/struct-runningstats): Streaming statistics tracker combining Welford's online algorithm for mean/variance with a TDigest for streaming percentile estimation.
