Struct MemoryMappedLoader 

pub struct MemoryMappedLoader { /* private fields */ }

Memory-mapped data loader for large datasets

This provides a way to access file data directly without loading it entirely into memory. Useful for working with datasets larger than available RAM.

Implementations

impl MemoryMappedLoader

pub fn new<P: AsRef<Path>>(file_path: P) -> Result<Self>

Create a new memory-mapped loader

Arguments

• file_path - Path to the file to be memory-mapped

pub fn file_path(&self) -> &Path

Get the file path

pub fn file_size(&self) -> Result<u64>

Get file size in bytes

pub fn load_slice(&self, _offset: usize, _length: usize) -> Result<&[u8]>

Load data without copying (placeholder implementation)

In a full implementation with memmap2 dependency, this would return a slice directly from the memory-mapped file.

pub fn can_map(&self) -> bool

Check if the file can be memory-mapped
