Struct OnceCellTocTouRule

Source

pub struct OnceCellTocTouRule { /* private fields */ }

Expand description

Detects potential TOCTOU (Time-of-check to time-of-use) races with OnceCell.

Pattern: Checking OnceCell::get() then calling get_or_init() based on result creates a race window where another thread may initialize between check and use.
