Trait Implementations

impl Stream for MemoryStream8

fn close(&mut self) -> Option<stream_result_t>

This function is called before closing the stream. It returns the current stream counters, or None if the stream may not be closed.

fn get_rock(&self) -> u32

Gets the rock for the stream. This is an arbitrary u32 that was provided on creation.

fn set_position(&mut self, pos: i32, mode: seekmode)

Set current position for reading/writing in the stream.

fn get_position(&mut self) -> u32

Get current position for reading/writing in the stream.

fn put_buffer(&mut self, buf: &[u8]) -> strid_t

Write to the stream. Optionally returns a stream id to mirror to.

fn put_buffer_uni(&mut self, buf: &[u32]) -> strid_t

Write unicode code points to the stream. Optionally returns a stream id to mirror to.

fn set_style(&mut self, _styl: Style) -> strid_t

Set current style. Streams that don’t have a concept of style can simply ignore this. Optionally returns a stream id to mirror to.

fn get_buffer(&mut self, buf: &mut [u8]) -> u32

Read from the stream.

fn get_buffer_uni(&mut self, buf: &mut [u32]) -> u32

Read unicode code points from the stream.

fn set_di_rock(&mut self, girock: rock)

Set dispatch rock. This is an arbitrary value stored by the Glk client in the stream object.

fn get_di_rock(&self) -> rock

Get dispatch rock.
