Expand description

Fallible memory write from a VmReader.

Required Methods§

Source

fn write_fallible( &mut self, reader: &mut VmReader<'_, F>, ) -> Result<usize, (Error, usize)>

Writes all data from the reader until one of the three conditions is met:

  1. The reader has no remaining data.
  2. The writer has no available space.
  3. The reader/writer encounters some error.

On success, the number of bytes written is returned; On error, both the error and the number of bytes written so far are returned.
