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

) {

alias OverflowCallback = void function(ref Composer, size_t numCharsAttempted);

this(Char[] buffer, OverflowCallback callback);

this(OverflowCallback callback);

this(Char[] buffer);

size_t messageLength [@property getter];

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

size_t bufferSize [@property getter];

void clear();

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

Composer write(A args);

}

Functions

clear void clear(): Clears the composer of any previously written characters.
setBuffer void setBuffer(Char[] buffer, size_t numCharsWritten): 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

bufferSize size_t bufferSize [@property getter]: Undocumented in source. Be warned that the author may not have intended to support it.
message immutable(Char[]) message [@property getter]
messageLength size_t messageLength [@property getter]
