Custom exception types and argument validation helpers for the Lyo library suite.

Common utilities, extensions, enums, JSON converters, and helper classes for the Lyo library suite.

Result, Error, Option, and validation primitives for the Lyo library suite.

Metrics collection and reporting library with support for counters, timers, and snapshots. Provides a pluggable metrics interface for integration with various metrics backends.

Digests, hex encoding, hashing streams, non-cryptographic checksums (CRC/Adler), lightweight file fingerprints (non-security), and optional hashing service.

Common stream implementations including TeeStream, CountingStream, ProgressStream, and ConcatenatedStream for the Lyo library suite. Incremental hashing: see Lyo.Hashing.

Date and time utilities and services for the Lyo library suite.

Query models for building and representing queries - QueryNode, QueryRequest, ConditionNode, SortBy, builders. Shared by Lyo.Query and Lyo.Api.

Interface for services that report their health. IFileStorageService, ICacheService, IMqService extend IHealth. CheckHealthAsync returns HealthResult with status, timings, and metadata.

API models and data transfer objects for the Lyo API library suite.

Key management interface and local implementation for encryption key storage, versioning, and rotation.

A production-ready .NET compression library providing efficient, thread-safe compression for the built-in BCL algorithms (GZip, Deflate, and on net10+ Brotli, ZLib). Additional algorithms (LZ4, LZMA, Snappier,... More information

Multi-ecosystem package catalog types and IPackageMetadataStore for stack traces and persistence adapters.

Diagnostic utilities for classifying exceptions, decoding and sanitising stack traces, and enriching structured logs for observability.

A production-ready .NET encryption library providing secure, authenticated encryption with support for multiple algorithms (AES-GCM, ChaCha20Poly1305, RSA), key management, and envelope encryption patterns.

API client library for consuming Lyo APIs.

Shared entity reference (EntityRef), composite id encoding, optional logical CLR type names, JSON converter, and association row contracts for Lyo modules. No database dependency.

Cache service abstractions and local IMemoryCache implementation.

Temp file and directory service with session tracking, logging, and metrics support.

Mutable data table with headers, rows, footer, thin cells, and a sparse optional format map. Used for CSV, XLSX, PDF data and programmatic table construction.
