Unlike a regular +/// trie, the edges of a radix tree can be labeled with sequences of characters +/// as well as single characters. This makes radix trees more efficient for +/// storing sparse data sets, where many nodes in a regular trie would have +/// only one child. +/// +/// This implementation supports arbitrary key types that can be iterated over +/// (e.g., `std::string`, `std::vector<char>`, `ArrayRef<char>`). The key type +/// must provide `begin()` and `end()` for iteration. +/// +/// The tree stores `std::pair<const KeyType, T>` as its value type. +/// +/// Example usage: +/// \code +/// llvm::RadixTree<StringRef, int> Tree; +/// Tree.emplace("apple", 1); +/// Tree.emplace("grapefruit", 2); +/// Tree.emplace("grape", 3); +/// +/// // Find prefixes +/// for (const auto &[Key, Value] : Tree.find_prefixes("grapefruit juice")) { +/// // pair will be {"grape", 3} +/// // pair will be {"grapefruit", 2} +/// llvm::outs() << Key << ": " << Value << "\n"; +/// } +/// +/// // Iterate over all elements +/// for (const auto &[Key, Value] : Tree) +/// llvm::outs() << Key << ": " << Value << "\n"; +/// \endcode +/// +/// \note +/// The `RadixTree` takes ownership of the `KeyType` and `T` objects +/// inserted into it.
