pub struct SizeHint { /* private fields */ }
Expand description
A BufStream
size hint
The default implementation returns:
- 0 for
available
- 0 for
lower
None
forupper
.
Implementations
sourceimpl SizeHint
impl SizeHint
sourcepub fn lower(&self) -> u64
pub fn lower(&self) -> u64
Returns the lower bound of data that the BufStream
will yield before
completing.
