FixedString

FixedString128

An unmanaged string in UTF-8 format that contains its own fixed-size buffer of the given size in bytes. The string is NOT guaranteed to be null-terminated, though in many cases it may be by accident. No memory is ever allocated, and no attempt is made to share memory when strings are copied. Since this structure is not generic and needs no disposing, it can exist inside ECS components, can be put in a FixedArray, FixedList or FixedHashMap, and can be a data member of unmanaged structs that are allocated from the unmanaged heap. This string is entirely compatible with Burst compilation.

The binary layout of this string is guaranteed, for now and all time, to be two bytes of little-endian length, followed by a contiguous array of bytes with that length, with no padding in between. This is intentionally identical to FixedList of byte, which is guaranteed to always have the same memory layout.

Those who need more than 65,535 contiguous items should allocate from the heap, as storing that many things contiguously in a C# struct is likely to result in much wasted time, as the compiler copies the struct often.
