ludus::foundation::StringIndex¶

Struct

Index is meaningful only inside its enclosing table/snapshot.

Never persist a runtime NameId or compare indices across dictionaries.

#include <ludus/foundation/strings/string_table.hpp>

struct ludus::foundation::StringIndex final

Static fields¶

static constexpr uint32 ludus::foundation::StringIndex::INVALID_VALUE = 0xffffffffU

Reserved invalid index value (0xffffffff); never names an entry.

Tables and dictionaries therefore hold fewer than 2^32 entries. Owners that store indices may also use it to mark unused slots.

Related types: uint32

uint32 ludus::foundation::StringIndex::Value {INVALID_VALUE}

Zero-based entry index; the default is INVALID_VALUE. In a StringTable, index zero is the empty spelling. Range checks belong to the owning table.

Related types: uint32

constexpr bool operator==(StringIndex, StringIndex) noexcept=default

Compares raw index values; meaningful only for indices of the same table or dictionary.
