Trait re_sdk::external::arrow2::trusted_len::TrustedLen
pub unsafe trait TrustedLen: Iterator { }
Expand description
An iterator of known, fixed size.
A trait denoting Rusts’ unstable TrustedLen.
This is re-defined here and implemented for some iterators until std::iter::TrustedLen
is stabilized.
§Safety
This trait must only be implemented when the contract is upheld. Consumers of this trait must inspect Iterator::size_hint()’s upper bound.
