Struct termion::AsyncReader
source · pub struct AsyncReader { /* private fields */ }
Expand description
An asynchronous reader.
This acts as any other stream, with the exception that reading from it won’t block. Instead, the buffer will only be partially updated based on how much the internal buffer holds.

source§fn read(&mut self, buf: &mut [u8]) -> Result<usize>
fn read(&mut self, buf: &mut [u8]) -> Result<usize>
Read from the byte stream.
This will never block, but try to drain the event queue until empty. If the total number of bytes written is lower than the buffer’s length, the event queue is empty or that the event stream halted.
