Detailed Description

A memory-mapped file source for efficiently reading files line by line.

MappedFileSource uses memory-mapped file techniques to handle files, allowing for high-performance sequential file reading.

Note: The file is mapped in read-only mode, ant it is freed once the MappedFileSource is destroyed.
