To simplify access to C++ array containers (aka std::vector), we use std::span-like structs to store a pointer to data and array length. There are two important notes about using these structs:

• if a function returns a pointer to a vector-like struct, you must call mrVector*Free function

if any operation resizes the underlying vector, the data pointer might be invalidated; it's better to call mrVector*Invalidate to update the pointer after any operation with the vector
