+ // of whatever the offsets in the vector need, the bit-widths of the strings
+ // are not stored(!) <- the actual design flaw.
+ // Note that even in the fixed code, we continue to serialize the elements of
+ // FBT_VECTOR_STRING as FBT_STRING, since there may be old code out there
+ // reading new data that we want to continue to function.

+ // field, and instead treat these strings as FBT_KEY (null-terminated), so we
+ // can deal with strings of arbitrary length. This of course truncates strings

+ // since it would read the high-byte of the 16-bit length.
+ // This should now correctly test the full 300 bytes, using AsKey():
+ TEST_EQ_STR(vec[0].AsKey(), test_data.c_str());

+ // accessor objects now use a cached size that can come from a key as well.

+ // you could consider using AsKey instead of AsString for a) documenting
+ // that you are accessing keys, or b) a speedup if you don't actually use
+ // the string size.
+ // For new data, or data that doesn't need to be backwards compatible,
+ // instead serialize as FBT_VECTOR (call EndVector with typed = false, then
+ // read elements with AsString), or, for maximum compactness, use
+ // FBT_VECTOR_KEY (call slb.Key above instead, read with AsKey or AsString).
