pub fn decode_stream(
reader: &mut impl Read,
ignore_garbage: bool,
writer: &mut impl Write,
) -> Result<()>Expand description
Stream-decode from a reader to a writer. Used for stdin processing. Fused single-pass: read chunk -> strip whitespace -> decode immediately. Uses 16MB read buffer to reduce syscalls and memchr2-based SIMD whitespace stripping for the common case (only \n and \r whitespace in base64 streams).
