Streams

Buffered

Buffers the flow of data from a upstream input. A downstream neighbour can locate and use this buffer instead of creating another instance of their own.

(note that upstream is closer to the source, and downstream is further away)

BufferedInput, BufferedOutput are streams buffer the flow of data from a upstream output. A downstream neighbour can locate and use this buffer instead of creating another instance of their own.

DataFile

DataFileInput, DataFileOutput composes a seekable file with buffer. A seek causes the buffer to be cleared or flushed.

Data

DataInput
A simple way to read binary data from an arbitrary InputStream, such as a file:

auto input = new DataInput (new File("path"));
auto x = input.int32;
auto y = input.float64;
input.array (new char[10]);
input.close;

DataOutput
A simple way to write binary data to an arbitrary OutputStream, such as a file:

auto output = new DataOutput (new File("path", File.WriteCreate));
output.int32 (1024);
output.float64 (3.14159);
output.array ("hello world");
output.flush.close;

Digest

DigestInput
Inject a digest filter into an input stream, updating the digest as information flows through it

DigestOutput
Inject a digest filter into an output stream, updating the digest as information flows through it. Here's an example where we calculate an MD5 digest as a side-effect of copying a file:

auto output = new DigestOutput(new File("output", File.WriteCreate), new Md5);
output.copy (new FileInput("input"));

Stdout.formatln ("hex digest: {}", output.digest.hexDigest);

Endian

Streams for swapping endian-order. The stream is treated as a set of same-sized elements. Note that partial elements are not mutated

EndianInput and EndianOutput

Format

Simple way to hook up a text formatter to an arbitrary OutputStream, such as a file:

auto output = new FormatOutput!(char) (new File("path", File.WriteCreate));
output.formatln ("{} green bottles", 10);
output.flush.close;

Greedy

GreedyOutput
A conduit filter that ensures its output is written in full

GreedyInput
A conduit filter that ensures its input is read in full

Lines

LineInput
Simple way to hook up a line-tokenizer to an arbitrary InputStream, such as a file conduit:

auto input = new LineInput (new File("path"));
foreach (line; input)
            ...
input.close;

Map

MapInput!(T) Provides load facilities for a properties stream. That is, a file or other medium containing lines of text with a name=value layout

MapOutput!(T) Provides write facilities on a properties stream. That is, a file or other medium which will contain lines of text with a name=value layout

Snoop

SnoopInput, SnoopOutput Streams to expose call behaviour. By default, activity trace is sent to Cerr.

This is useful for logging/debugging the stream calls.

TextFile

TextFileInput and TextFileOutput
Composes a file with line-oriented input

Typed

TypedInput!(T) and TypedOutput!(T)
Streams to expose simple native types as discrete elements. I/O is buffered and should yield fair performance.

UtfStream

UtfInput!(T,S) and UtfOutput!(S,T)
UTF conversion streams, supporting cross-translation of char, wchar and dchar variants. For supporting endian variations, configure the appropriate EndianStream upstream of this one (closer to the source)
