Trait Implementations

impl<'a, D, RWType> ErrorType for BufferOperation<'a, D, RWType>

type Error = ErrorKind

Error type of all the IO operations on this type.

impl<'a, D, RWType> Read for BufferOperation<'a, D, RWType>

where D: BufferDevice, RWType: ReadCapability,

fn read(&mut self, buf: &mut [u8]) -> Result<usize, Self::Error>

Read some bytes from this source into the specified buffer, returning how many bytes were read.

fn read_exact( &mut self, buf: &mut [u8], ) -> Result<(), ReadExactError<Self::Error>>

Read the exact number of bytes required to fill buf.

impl<'a, D, RWType> Read for BufferOperation<'a, D, RWType>

where D: AsyncBufferDevice, RWType: ReadCapability,

async fn read(&mut self, buf: &mut [u8]) -> Result<usize, Self::Error>

Read some bytes from this source into the specified buffer, returning how many bytes were read.

async fn read_exact( &mut self, buf: &mut [u8], ) -> Result<(), ReadExactError<Self::Error>>

Read the exact number of bytes required to fill buf.

impl<'a, D, RWType> Write for BufferOperation<'a, D, RWType>

where D: BufferDevice, RWType: WriteCapability,

fn write(&mut self, buf: &[u8]) -> Result<usize, Self::Error>

Write a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> Result<(), Self::Error>

Flush this output stream, blocking until all intermediately buffered contents reach their destination.

fn write_all(&mut self, buf: &[u8]) -> Result<(), Self::Error>

Write an entire buffer into this writer.

fn write_fmt( &mut self, fmt: Arguments<'_>, ) -> Result<(), WriteFmtError<Self::Error>>

Write a formatted string into this writer, returning any error encountered.

impl<'a, D, RWType> Write for BufferOperation<'a, D, RWType>

where D: AsyncBufferDevice, RWType: WriteCapability,

async fn write(&mut self, buf: &[u8]) -> Result<usize, Self::Error>

Write a buffer into this writer, returning how many bytes were written.

async fn flush(&mut self) -> Result<(), Self::Error>

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

async fn write_all(&mut self, buf: &[u8]) -> Result<(), Self::Error>

Write an entire buffer into this writer.
