std.outbuffer

Serialize data to ubyte arrays.

class OutBuffer;
OutBuffer provides a way to build up an array of bytes out of raw data. It is useful for things like preparing an array of bytes to write out to a file. OutBuffer's byte order is the format native to the computer. To control the byte order (endianness), use a class derived from OutBuffer. OutBuffer's internal buffer is allocated with the GC.
pure nothrow @safe ubyte[] toBytes();
Convert to array of bytes.
pure nothrow @trusted void reserve(size_t nbytes);
Preallocate nbytes more to the size of the internal buffer.
This is a speed optimization, a good guess at the maximum size of the resulting buffer will improve performance by eliminating reallocations and copying.
alias put = write;
put enables OutBuffer to be used as an OutputRange.
pure nothrow @safe void write(const(ubyte)[] bytes);
pure nothrow @safe void write(byte b);
pure nothrow @safe void write(char c);
pure nothrow @safe void write(dchar c);
pure nothrow @safe void write(short s);
pure nothrow @safe void write(int i);
pure nothrow @safe void write(long l);
Append data to the internal buffer.
pure nothrow @safe void fill0(size_t nbytes);
Append nbytes of 0 to the internal buffer.
pure nothrow @safe void alignSize(size_t alignsize);
0-fill to align on power of 2 boundary.
pure nothrow @safe void align2();
Optimize common special case alignSize(2)
pure nothrow @safe void align4();
Optimize common special case alignSize(4)
const pure nothrow @safe string toString();
Convert internal buffer to array of chars.
nothrow @trusted void vprintf(string format, va_list args);
Append output of C's vprintf() to internal buffer.
@trusted void printf(string format, ...);
Append output of C's printf() to internal buffer.
void writef(Char, A...)(in Char[] fmt, A args);
Formats and writes its arguments in text format to the OutBuffer.
Parameters:
Char[] fmt format string as described in std.format.formattedWrite
A args arguments to be formatted
See Also:
writef">std.stdio.writef; std.format.formattedWrite;
Examples:
OutBuffer b = new OutBuffer();
b.writef("a%sb", 16);
assert(b.toString() == "a16b");
void writefln(Char, A...)(in Char[] fmt, A args);
Formats and writes its arguments in text format to the OutBuffer, followed by a newline.
Parameters:
Char[] fmt format string as described in std.format.formattedWrite
A args arguments to be formatted
See Also:
writefln">std.stdio.writefln; std.format.formattedWrite;
Examples:
OutBuffer b = new OutBuffer();
b.writefln("a%sb", 16);
assert(b.toString() == "a16b\n");
pure nothrow @safe void spread(size_t index, size_t nbytes);
At offset index into buffer, create nbytes of space by shifting upwards all data past index.
