-----------------------------------
Summary: [Rust] Potential crash when creating arrays from
Iterators if size_hint is not correct
Key: ARROW-10886
URL: https://issues.apache.org/jira/browse/ARROW-10886
Project: Apache Arrow
Issue Type: Bug
Reporter: Andrew Lamb
It appears that the code that implements converting iterators to arrow arrays
effectively relies on size_hint to return the precise size of the iterator
otherwise it will crash (maybe) -- but I think the intention of size_hint is,
as the name suggests, a hint.
The goal of this ticket is to remove the assumption in the code that size_hint
must return a value as well as the assumption that it is accurate.
