Detailed Description

An output stream that writes data to an internal memory buffer.

This stream implementation uses fmt::memory_buffer internally to accumulate character or binary data. It is typically used when dynamically collecting output into a contiguous memory block, for later retrieval or further processing.

The data written to this stream is stored in a resizable buffer, which can be accessed or converted to a BufferHandle after writing is complete.

Note

This stream is not thread-safe.

Decrement the internal reference counter.

When the internal counter reaches zero the object is deleted. Releasing already disposed object causes undefined behavior.
