toml::path_component class

Represents a single component of a complete 'TOML-path': either a key or an array index.

Constructors, destructors, conversion operators

path_component(): Default constructor (creates an empty key).
path_component(size_t index) noexcept: Constructor for a path component that is an array index.
path_component(std::string_view key): Constructor for a path component that is a key string.
path_component(std::wstring_view key): Constructor for a path component that is a key string.
path_component(const path_component& pc): Copy constructor.
path_component(path_component&& pc) noexcept: Move constructor.
~path_component() noexcept: Destructor.

auto operator=(const path_component& rhs) -> path_component&: Copy-assignment operator.
auto operator=(path_component&& rhs) -> path_component& noexcept: Move-assignment operator.
auto operator=(size_t new_index) -> path_component& noexcept: Assigns an array index to this path component.
auto operator=(std::string_view new_key) -> path_component&: Assigns a path key to this path component.
auto operator=(std::wstring_view new_key) -> path_component&: Assigns a path key to this path component.
auto type() const -> path_component_type noexcept: Retrieve the type of this path component, either path_component::key or path_component::array_index.

auto index() const -> size_t noexcept: Returns the array index (const lvalue overload).
operator size_t() const explicit noexcept: Returns the array index (const lvalue).

auto operator!=(const path_component& lhs, const path_component& rhs) -> bool noexcept: Returns true if two path components do not represent the same key or array index.
auto operator==(const path_component& lhs, const path_component& rhs) -> bool noexcept: Returns true if two path components represent the same key or array index.

auto key() const -> const std::string& noexcept: Returns the key string.
operator const std::string&() const explicit noexcept: Returns the key string.
