Bodu.Collections.Concurrent

API stability — Stable. The public API surface is committed; breaking changes are reserved for a major-version bump per SemVer.

The thread-safe collection variants of the Bodu collection catalogue: a lock-free bounded MPMC ring buffer, a lock-free split-ordered concurrent set, and a lock-striped bounded cache. The original two types were split out of Bodu.Collections with the namespace unchanged — code written against Bodu.Collections.Generic.Concurrent keeps compiling; only the package reference changes. All collections implement the standard BCL interfaces and ship struct enumerators over best-effort snapshots. The package references Bodu.Collections (and transitively Bodu.Core).

Installation

dotnet add package Bodu.Collections.Concurrent

Targets net8.0. Depends on Bodu.Collections.

Collections

Type Namespace Summary
ConcurrentCircularBuffer<T> Bodu.Collections.Generic.Concurrent Lock-free (Vyukov MPMC) fixed-capacity FIFO ring buffer with optional overwrite-on-full and eviction events
ConcurrentHashSet<T> Bodu.Collections.Generic.Concurrent Lock-free split-ordered concurrent set implementing ISet<T>, with comparer injection and snapshot enumeration
ConcurrentEvictingDictionary<TKey,TValue> Bodu.Collections.Generic.Concurrent Lock-striped bounded cache — the thread-safe variant of EvictingDictionary<TKey,TValue> with all six eviction policies (FIFO/LRU/LFU/MRU/SecondChance/Random), optional TTL expiry, single-flight GetOrAdd, and a post-commit ItemEvicted event. Eviction order is exact per segment, approximate globally

For the single-threaded counterparts (CircularBuffer<T>, EvictingDictionary<TKey,TValue>, Deque<T>, and the wider catalogue), see the Bodu.Collections package.

Testing

The types are verified through the shared contract-test bases in Bodu.Test (collection, set, read-only-collection, enumerator, non-generic, and debug-view contracts) plus concurrency-specific suites: multi-producer/multi-consumer stress runs, overwrite contention, slot-layout and snapshot-stability checks, and — for the evicting dictionary — a differential suite that replays scripted workloads against the non-concurrent EvictingDictionary oracle to pin per-segment eviction parity.
