Large Files and Virtualization

HexView is designed around large-file access.

Why It Scales

MemoryMappedLineReader avoids loading the whole file into memory
the control renders only visible lines
search works in chunks instead of on one giant in-memory buffer
overwrite edits are sparse and keyed by offset

Practical Notes

prefer MemoryMappedLineReader for real files
keep expensive transformations out of Render
use DifferencesProvider and EditedOffsetsProvider to feed only visible ranges

Insert Mode Caveat

Insert mode is more flexible but also more complex because logical length diverges from physical length. Use overwrite mode when you do not need structural edits.
