Trait Implementations

impl<'a> Writer<'a> for FixedLengthFileWriter

fn finish(&mut self)

Flush any remaining bytes in the output stream, ensuring that all bytes are written.

Panics

If not all bytes could be written due to any I/O errors or by reaching EOF.

fn write(&mut self, buffer: &[u8])

Write the entire buffer to the file by continuously calling write.

Panics

Iff any I/O error was generated and then unwrapped.

fn try_finish(&mut self) -> Result<()>

Try and flush any remaining bytes in the output stream, ensuring that all bytes are written.

Errors

If not all bytes could be written due to any I/O errors or by reaching EOF.

fn try_write(&mut self, buffer: Self::Buffer) -> Result<()>

Try to write the entire buffer to the file by continuously calling write.

Errors

Each call to write inside this function might generate an I/O error indicating that the operation could not be completed. If an error is returned, then this is guaranteed to happen before any bytes are actually written from the buffer.
