Struct TakeRange 

pub struct TakeRange<T: ?Sized> { /* private fields */ }

An adapter that limits the range of a ReadAt or WriteAt.

This can be obtained by calling Size::take_range.

Implementations

impl<T: ?Sized> TakeRange<T>

pub fn get_ref(&self) -> &T

Gets a reference to the underlying stream.

pub fn get_mut(&mut self) -> &mut T

Gets a mutable reference to the underlying stream.

pub fn into_inner(self) -> T

where T: Sized,

Consumes the TakeRange, returning the wrapped stream.

Trait Implementations

impl<T: ReadAt + ?Sized> ReadAt for TakeRange<T>

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

Reads a number of bytes starting from a given offset.

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

Reads the exact number of byte required to fill buf from the given offset.

fn read_vectored_at( &self, bufs: &mut [IoSliceMut<'_>], offset: u64, ) -> Result<usize>

Like read_at, except that it reads into a slice of buffers.

impl<T: Size + ?Sized> Size for TakeRange<T>

fn size(&self) -> Result<u64>

Returns the size of the stream.

fn take_range(self, range: impl RangeBounds<u64>) -> TakeRange<Self>

where Self: Sized,

Creates an adapter which only reads and write within the given range.

impl<T: WriteAt + ?Sized> WriteAt for TakeRange<T>

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

Writes a number of bytes starting from a given offset.

fn write_all_at(&self, buf: &[u8], offset: u64) -> Result<()>

Attempts to write an entire buffer starting from a given offset.

fn write_vectored_at(&self, bufs: &[IoSlice<'_>], offset: u64) -> Result<usize>

Like write_at, except that it writes from a slice of buffers.

fn flush(&self) -> Result<()>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.
