IfdPointer.Notice that this does not take an argument, a 64-bit IFD is always allowed. If the difference is crucial and you do not want to be permissive you're expected to filter this out before.
For compatibility the smaller sized tags should always be allowed i.e. you might use a non-bigtiff's directory and its tag types and move it straight to a bigtiff. For instance the SubIFD tag is defined as
LONG or IFD:fn into_string(self) -> TiffResult<String>fn into_u32_vec(self) -> TiffResult<Vec<u32>>fn into_u8_vec(self) -> TiffResult<Vec<u8>>fn into_u16_vec(self) -> TiffResult<Vec<u16>>fn into_i32_vec(self) -> TiffResult<Vec<i32>>fn into_f32_vec(self) -> TiffResult<Vec<f32>>fn into_f64_vec(self) -> TiffResult<Vec<f64>>fn into_u64_vec(self) -> TiffResult<Vec<u64>>fn into_i64_vec(self) -> TiffResult<Vec<i64>>fn into_ifd_vec(self) -> TiffResult<Vec<IfdPointer>>
