AsyncStreamReader

sail::exec

Struct AsyncStreamReader 

Source 
pub struct AsyncStreamReader { /* private fields */ }
Expand description

An async cursor over one live output stream, the awaiting counterpart of StreamReader. AsyncStreamReader::next yields the next chunk without parking a runtime thread, so many streams can be read on one event loop.

Implementations§

Source§

impl AsyncStreamReader

Source

pub async fn next(&mut self) -> Option<String>

The next retained chunk, or None once the stream is closed and fully drained. A reader that falls more than the buffer cap behind skips the dropped head rather than stalling.
