`read_zero_byte_vec` refactor for better heuristics Fixes #9274 Previously, the implementation of `read_zero_byte_vec` only checks for the next statement after the vec init. This fails when there is a block with statements that are expanded and walked by the old visitor. This PR refactors so that: 1. It checks if there is a `resize` on the vec 2. It works on blocks properly e.g. This should properly lint now: ``` let mut v = Vec::new(); { f.read(&mut v)?; //~^ ERROR: reading zero byte data to `Vec` } ``` changelog: [`read_zero_byte_vec`] Refactored for better heuristics |
