Function rustc_demangle::demangle_stream

pub fn demangle_stream<R: BufRead, W: Write>(
    input: &mut R,
    output: &mut W,
    include_hash: bool
) -> Result<()>

Available on crate feature std only.

Process a stream of data from input into the provided output, demangling any symbols found within.

Note that the underlying implementation will perform many relatively small writes to the output. If the output is expensive to write to (e.g., requires syscalls), consider using std::io::BufWriter.
