Struct dsi_bitstream::utils::CountBitWriter

pub struct CountBitWriter<E: Endianness, BW: BitWrite<E>, const PRINT: bool = false> {
    pub bits_written: usize,
    /* private fields */
}

A wrapper around a BitWrite that keeps track of the number of bits written and optionally prints on standard error the operations performed on the stream.

Fields

bits_written: usize

The number of bits written so far on the underlying BitWrite.
