Struct MmapRegion 

pub struct MmapRegion { /* private fields */ }

Memory-mapped region

Implementations

impl MmapRegion

pub fn new(file: &File) -> Result<Self>

Create a new memory-mapped region for a file

pub fn new_with_readahead(file: &File) -> Result<Self>

Create with advisory read-ahead hint

pub fn len(&self) -> usize

Get the length of the mapped region

pub fn is_empty(&self) -> bool

Check if empty

pub fn as_slice(&self) -> &[u8]

Get a slice of the mapped region

Safety

The returned slice is only valid as long as the MmapRegion exists and the underlying file is not modified.

pub fn slice(&self, range: Range<usize>) -> Option<&[u8]>

Get a subslice of the mapped region

pub fn prefetch(&self, range: Range<usize>)

Prefetch a range of data
