[−][src]Struct tokio_buf::SizeHint
A BufStream
size hint
The default implementation returns:
- 0 for
available
- 0 for
lower
None
forupper
.
Methods
impl SizeHint
[src]
pub fn new() -> SizeHint
[src]
Returns a new SizeHint
with default values
pub fn lower(&self) -> u64
[src]
Returns the lower bound of data that the BufStream
will yield before
completing.
pub fn set_lower(&mut self, value: u64)
[src]
pub fn upper(&self) -> Option<u64>
[src]
Returns the upper bound of data the BufStream
will yield before
completing, or None
if the value is unknown.
pub fn set_upper(&mut self, value: u64)
