Function low_precision_storage_bytes 

Source 
pub const fn low_precision_storage_bytes(
    dtype: DType,
    elements: usize,
) -> Option<usize>
Expand description

Return the packed byte count for an INT4, INT8, FP8E4M3, or FP8E5M2 tensor.

INT4 elements are packed low nibble first. None means that dtype is not one of these low-precision types. The packed byte count itself cannot overflow usize.
