Module rustc_mir_transform::known_panics_lint

A lint that checks for known panics like overflows, division by zero, out-of-bound access etc. Uses const propagation to determine the values of operands during checks.

Structs

• CanConstProp
  A visitor that determines locals in a MIR body that can be const propagated
• ConstPropagator 🔒
  Visits MIR nodes, performs const propagation and runs lint checks as it goes
• KnownPanicsLint

Enums

• ConstPropMode
  The mode that ConstProp is allowed to run in for a given Local.
• Value 🔒

Constants

• MAX_ALLOC_LIMIT 🔒
  The maximum number of bytes that we’ll allocate space for a local or the return value. Needed for #66397, because otherwise we eval into large places and that can cause OOM or just Severely regress performance.
