Time
This project is a comprehensive library for handling dates, times, durations, and UTC offsets within the Rust programming language. It provides a framework for temporal data processing, utilizing specialized structures to maintain nanosecond precision for high-accuracy scheduling and logging requirements.
The library distinguishes itself through extensive use of compile-time evaluation, which allows for the generation and validation of temporal values during the build process to eliminate runtime overhead. It employs strongly-typed primitives and overflow-checked arithmetic to ensure that all mathematical operations and data manipulations remain safe and valid. Furthermore, the framework includes cross-platform utilities for resolving local system offsets and managing time zone data across diverse operating environments.
Beyond its core processing capabilities, the library supports a broad range of temporal operations, including parsing and formatting strings according to international standards like ISO 8601 and RFC 3339. It also provides extended date range support for historical or long-term planning and integrates with the broader ecosystem through standardized traits for serialization, testing, and random number generation.
