Struct BlockLimitWrite

pub struct BlockLimitWrite<T: WriteAt> { /* private fields */ }

Limit the amount of data accepted in a single call to WriteAt (ReadAt is unaffected)

This is primarily useful for testing that handling of incomplete writes work properly.

Implementations

impl<T: WriteAt> BlockLimitWrite<T>

pub fn new(v: T, max_per_block: usize) -> Self

Trait Implementations

impl<T: Debug + WriteAt> Debug for BlockLimitWrite<T>

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

Formats the value using the given formatter.

impl<T: WriteAt> Deref for BlockLimitWrite<T>

type Target = T

The resulting type after dereferencing.

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

Dereferences the value.

impl<T: WriteAt> DerefMut for BlockLimitWrite<T>

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

Mutably dereferences the value.

impl<T: PartialEq + WriteAt> PartialEq for BlockLimitWrite<T>

fn eq(&self, other: &BlockLimitWrite<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: WriteAt + ReadAt> ReadAt for BlockLimitWrite<T>

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

impl<T: WriteAt> WriteAt for BlockLimitWrite<T>

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

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