Provided Methods

unsafe fn trust_my_length( self, length: usize, ) -> TrustMyLength<Self, Self::Item>

where Self: Sized,

Turn any iterator in a trusted length iterator

Safety

The given length must be correct.

fn collect_trusted<T>(self) -> T

where T: FromTrustedLenIterator<Self::Item>, Self: Sized + TrustedLen,

fn collect_reversed<T>(self) -> T

where T: FromIteratorReversed<Self::Item>, Self: Sized + TrustedLen,
