C4Core: A Practical C++ Utility Library

C4Core is a cross-platform C++ utility library that provides developers with many convenient features. The design goal of this library is to offer efficient, concise, and easy-to-use tools to help developers complete various tasks more effectively.

1. Main Features

(1) Character Conversion

C4Core provides efficient character conversion capabilities, including c4::to_chars and c4::from_chars. These functions can quickly convert numeric types to character representations or parse numeric values from characters. In terms of performance, C4Core’s character conversion functions perform excellently, with c4::to_chars<u8> achieving a write throughput of 526.86 MB/s and a read throughput of 163.06 MB/s. In comparison, the performance of the standard library’s std::to_chars<u8> and std::from_chars<u8> is slightly inferior.

(2) String Formatting and Parsing

C4Core offers powerful string formatting and parsing capabilities. It supports various formatting options, such as c4::fmt::overflow_checked, c4::fmt::real, and c4::fmt::boolalpha. These features help developers easily generate and parse complex string formats without manually concatenating strings.

(3) Data Structures

C4Core provides data structures such as c4::span and c4::blob. c4::span is a lightweight array view that allows developers to manipulate arrays without copying data. c4::blob is a dynamic memory buffer that conveniently manages dynamically allocated memory.

(4) Enumeration and Bitmask Operations

C4Core provides functions like c4::e2str and c4::str2e to convert enumeration values to strings or parse enumeration values from strings. Additionally, it offers c4::bm2str and c4::str2bm functions for bitmask conversions.

(5) Other Features

C4Core also provides many other practical features, such as Base64 encoding/decoding and fuzzy floating-point comparisons. These features can help developers work more conveniently and efficiently when handling various data.

2. Use Cases

The functionalities of C4Core are extensive and suitable for various development scenarios. For example, when handling file input and output, its efficient character conversion and string formatting capabilities can be utilized. When dealing with network data, its data structures and Base64 encoding/decoding features can be leveraged. Furthermore, C4Core’s cross-platform nature allows it to be used across different operating systems.

3. Advantages

The advantages of C4Core lie in its efficiency and ease of use. Its character conversion and string formatting functionalities are faster than similar features in the standard library. At the same time, C4Core offers a rich set of features while maintaining a simple interface. This allows developers to quickly get started and use it effectively.

4. Conclusion

C4Core is a powerful and efficient C++ utility library. It provides various functionalities, including character conversion, string formatting, and data structure operations. These features can help developers complete various tasks more efficiently. If you are looking for a simple, easy-to-use, and efficient utility library, C4Core is an excellent choice.
