The default implementation returns:

  • 0 for lower

Returns a new SizeHint with default values

Returns a new SizeHint with both upper and lower bounds set to the given value.

Returns the lower bound of data that the Body will yield before completing.

Set the value of the lower hint.

Panics

The function panics if value is greater than upper.

Returns the upper bound of data the Body will yield before completing, or None if the value is unknown.

Set the value of the upper hint value.
