nbuff 0.1.0

Memory buffer.

The main goal of this package is to minimize data movement when receiving from network and allow standard algorithms on received data.

Basically buffer is immutable(immutable(ubyte)[])[], but it support some useful Range properties, it

isInputRange!Buffer,
isForwardRange!Buffer,
hasLength!Buffer,
hasSlicing!Buffer,
isBidirectionalRange!Buffer,
isRandomAccessRange!Buffer

so it can be used with many range algorithms, but it supports several optimized methods like find, indexOf, splitOn, findSplitOn.

For example:

    Buffer httpMessage = Buffer();
    httpMessage.append("HTTP/1.1 200 OK\r\nContent-Type: text/plain\r");
    httpMessage.append("\n");
    httpMessage.append("Conte");
    httpMessage.append("nt-Length: 4\r\n");
    httpMessage.append("\r\n");
    httpMessage.append("body");
    writeln(httpMessage.splitOn('\n').map!"a.toString.strip");

prints:

["HTTP/1.1 200 OK", "Content-Type: text/plain", "Content-Length: 4", "", "body"]

At the same time:

• typeid(httpMessage.splitOn('\n')) - optimized, returns Buffer[]
• typeid(httpMessage.split('\n')) - from std.algorithms, returns Buffer[]
• typeid(httpMessage.splitter('\n')) - from std.algorithms, returns lazy Result

will give same results.

You can find examples in unittest section of buffer.d Buffer supports zero-copy (in most cases) append, split, slice, popFront and popBack, as long as some useful range primitives - find, indexOf, etc.
