Sourcepub fn new(reader: R, buffer_size: usize) -> Self
pub fn new(reader: R, buffer_size: usize) -> Self
Creates a new BufStreamReader with a specified buffer_size
.
This newly created object wraps another object which is Read.
buffer_size
- Size of the read buffer. BufStreamReader always tries to readbuffer_size
bytes from ` reader, but it is not guaranteed that the buffer actually holds that number of bytes (e.g. at the end of the stream)reader
- Reader which has to be wrapped
