Struct Take

pub struct Take<T> { /* private fields */ }

Limit the maximum offset of a WriteAt and/or ReadAt.

This can be useful when trying to simulate a fixed size item (like a block device) with a normal file.

Implementations

impl<T> Take<T>

pub fn new(v: T, max_offs: u64) -> Self

pub fn len(&self) -> u64

Trait Implementations

impl<T: Debug> Debug for Take<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> Deref for Take<T>

type Target = T

The resulting type after dereferencing.

fn deref<'a>(&'a self) -> &'a T

Dereferences the value.

impl<T> DerefMut for Take<T>

fn deref_mut<'a>(&'a mut self) -> &'a mut T

Mutably dereferences the value.

impl<T: PartialEq> PartialEq for Take<T>

fn eq(&self, other: &Take<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T: ReadAt> ReadAt for Take<T>

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

impl<T: WriteAt> WriteAt for Take<T>

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

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