fn data_size(&self) -> usize

Returns the number of bytes from the start up to including the last byte written in the stream that has not been truncated away.

Returns

the number of bytes written to the stream

source

fn steal_as_bytes(&self) -> Bytes

Returns data from the self as a glib::Bytes. self must be closed before calling this function.

Returns

the stream’s data
