Instance Method Detail
Closes the file descriptor resource.
Reads at least one byte from the file descriptor into slice.
Blocks the current fiber if no data is available for reading, continuing when available. Otherwise returns immediately.
Returns the number of bytes read (up to slice.size).
Returns 0 when EOF is reached.
Removes the file descriptor from the event loop. Can be used to free up memory resources associated with the file descriptor, as well as removing the file descriptor from kernel data structures.
Called by ::IO::FileDescriptor#finalize before closing the file
descriptor. Errors shall be silently ignored.
Writes at least one byte from slice to the file descriptor.
Blocks the current fiber if the file descriptor isn't ready for writing, continuing when ready. Otherwise returns immediately.
Returns the number of bytes written (up to slice.size).
