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.

This currently is implemented by buffering each line of input in memory, but that may be changed in the future. Symbols never cross line boundaries so this is just an implementation detail.
