stdmapstdstring

stdmapstdstring is a C++ utility that provides a simple, type-safe container for mapping string keys to string values. It is designed to ease common tasks involving configuration data, parameters, or other string-based key-value pairs by encapsulating a standard map interface tailored to std::string.

Implementation typically wraps a standard container such as std::map<std::string, std::string> or std::unordered_map<std::string, std::string>, offering a focused API. The class exposes operations to insert and update values, retrieve them by key, check for key existence, erase entries, and iterate over pairs. Common member functions include insert, emplace, operator[], at, find, contains (from C++20), erase, clear, size, and iteration begin/end. It may also provide conveniences such as to_string serialization or parsing from a delimited string.

Usage patterns include storing configuration parameters, passing around a collection of string-based options, or as a lightweight database of string mappings. Typical complexity is logarithmic for ordered maps and average constant time for hash-based variants; memory usage follows the underlying container.

Compared to a raw std::map<std::string, std::string>, stdmapstdstring offers a focused wrapper with a clear API and potential helper utilities, while relying on the same performance characteristics. It is compatible with the standard library and can be substituted by either std::map or std::unordered_map depending on the needs.
