Struct std::io::BufferedWriter

A buffered wrapper over an underlying writable stream.

Fields

• buf: &mut [u8]

• pos: usize

• inner: &mut W

Methods

• fn new(inner: &mut W, buf_size: usize) -> BufferedWriter<W>

  source

  Create a BufferedWriter with a heap-allocated buffer of the given size.

• fn from_slice(inner: &mut W, buf: &mut [u8]) -> BufferedWriter<W>

  source

  Creates a BufferedWriter from an existing-buffer, potentially avoiding a heap allocation.

• fn write(self: &mut BufferedWriter<W>, buf: &[u8]) -> Result<usize>

  source

  Write the buffer to the stream.

  Returns the number of bytes written. This may be less than the size of the buffer. See also write_all, which can be used to write the entire buffer.

• fn write_all(self: &mut BufferedWriter<W>, buf: &[u8]) -> Result<()>

  source

  Writes all the bytes in the buffer to the stream.

  If EOF is reached, returns Error::eof().

• fn flush(self: &mut BufferedWriter<W>) -> Result<()>

  source

  Flush the stream

  This may be a no-op, depending on the stream.

• fn free(self: &mut BufferedWriter<W>)

  source

  Frees the memory backing the object.

• fn move(self: &mut BufferedWriter<W>) -> BufferedWriter<W>

  source

  Creates a copy of the object, leaving an inert object behind.

  See Movable for details.

• fn write_str(self: &mut BufferedWriter<W>, buf: &[u8]) -> Result

  source

  Write a string

Mixins

• mixin Formatter<BufferedWriter<W>>

• fn write_byte(self: &mut Self, byte: u8) -> Result

  source

  Write a single character
