Struct FileRegion 

pub struct FileRegion<'a> { /* private fields */ }

Implementations

impl<'a> FileRegion<'a>

pub fn file_metadata(&self) -> Result<Metadata>

pub fn range(self) -> Range<u64>

pub fn len(&self) -> u64

pub fn is_empty(&self) -> bool

pub fn new(file: &File, range: Range<u64>) -> FileRegion<'_>

pub fn is_valid(&self) -> Result<bool>

pub fn from_file(file: &'a File) -> Result<FileRegion<'a>>

pub fn subregion(self, range: Range<u64>) -> Result<FileRegion<'a>>

Return a subregion. Checks for some inconsistencies but not all; use is_valid() to check consistency against the underlying file.

pub fn read(&mut self, offset: u64, buf: &mut [u8]) -> Result<usize>

pub fn write(&mut self, offset: u64, buf: &[u8]) -> Result<usize>
