}

A kind of panic, as reported to the user.

The discriminants are stable because they index into CategorySet.

Variants

Index = 0

Slice or array index out of bounds.

Overflow = 1

Arithmetic overflow. Only present when overflow checks are enabled.

DivideByZero = 2

Integer division by zero.

RemainderByZero = 3

Integer remainder by zero.

Unwrap = 4

Option::unwrap, Result::unwrap, expect, and friends.

Explicit = 5

panic!, assert!, unreachable!, todo!, and friends.

StrBoundary = 6

Slicing a str at a non-character boundary.

Borrow = 7

A RefCell borrow conflict.

Poison = 8

A poisoned Mutex or RwLock.

CapacityOverflow = 9

A collection grew past the maximum representable capacity.

AllocFailure = 10

The allocator could not satisfy a request.

RefCountOverflow = 11

An Rc or Arc strong count overflowed.

Fmt = 12

A panic raised from inside the formatting machinery.

NullDeref = 13

A null pointer was dereferenced.

MisalignedRef = 14

A reference was constructed from a misaligned pointer.

Unknown = 15

A panic whose origin the analysis could not classify.

UbCheck = 16

A standard library precondition check, present only in a build that has undefined behaviour checks turned on.

Foreign = 17

A call into foreign code, which has no Rust body to read.

DynCall = 18

A dynamic call, whose target set the analysis does not resolve.

FnPointer = 19

A call through a function pointer, whose target is unknown.

GenericBound = 20

A call that resolves only once a caller supplies concrete generic arguments, so what it reaches is the caller’s choice.
