Functions

decode_owned

Decode base64 from an owned Vec (in-place whitespace strip + decode).

decode_stream

Stream-decode from a reader to a writer. Used for stdin processing. Fused single-pass: read chunk → strip whitespace in-place → decode immediately.

decode_to_writer

Decode base64 data and write to output (borrows data, allocates clean buffer). When ignore_garbage is true, strip all non-base64 characters. When false, only strip whitespace (standard behavior).

encode_stream

Stream-encode from a reader to a writer. Used for stdin processing.

encode_to_writer

Encode data and write to output with line wrapping. Uses SIMD encoding with fused encode+wrap for maximum throughput.
