Composer

The Composer is a configurable string joiner.

It was originally designed to be a way to allow assert messages with runtime parameters in functions marked @nogc.

struct Composer (

Char

size_t buffSize = runtime

OverflowPolicy policy = OverflowPolicy.assertFalse

) {

size_t messageLength [@property getter];

immutable(Char[]) message [@property getter];

void clear();

void setBuffer(Char[] buffer, size_t numCharsWritten = 0);

Composer write(A args);

Char[] _buffer;

Char[buffSize] _buffer;

OverflowCallback _overflowCallback;

}

Members

Functions

clear void clear(): Clears the composer of any previously written characters.
setBuffer void setBuffer(Char[] buffer, size_t numCharsWritten = 0): Set the composer's buffer to buffer. This is to enable the creation of dynamic buffers.
write Composer write(A args): Composes a message from arguments. Anything that was previously written to the composer will be cleared.

Properties

message immutable(Char[]) message [@property getter]
