Struct SizeHint

pub struct SizeHint { /* private fields */ }
Expand description

A Body size hint

The default implementation returns:

  • 0 for lower
  • None for upper.

Implementations§

§

impl SizeHint

pub fn new() -> SizeHint

Returns a new SizeHint with default values

pub fn with_exact(value: u64) -> SizeHint

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

pub fn lower(&self) -> u64

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

pub fn set_lower(&mut self, value: u64)

Set the value of the lower hint.

§Panics

The function panics if value is greater than upper.

pub fn upper(&self) -> Option<u64>

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

pub fn set_upper(&mut self, value: u64)

Set the value of the upper hint value.

§Panics

This function panics if value is less than lower.

pub fn exact(&self) -> Option<u64>

Returns the exact size of data that will be yielded if the lower and upper bounds are equal.

pub fn set_exact(&mut self, value: u64)

Set the value of the lower and upper bounds to exactly the same.
