Expand description

Stores trace message with backtrace.

Variants

`User(Error)`

A user-raised trap through raise_user_trap.

`Jit`

Fields

pc: usize

The program counter in JIT code where this trap happened.

backtrace: Backtrace

Native stack backtrace at the time the trap occurred

A trap raised from jit code

`Wasm`

Fields

trap_code: TrapCode

Code of the trap.

backtrace: Backtrace

Native stack backtrace at the time the trap occurred

A trap raised from a wasm libcall

`OOM`

Fields

backtrace: Backtrace

Native stack backtrace at the time the OOM occurred

A trap indicating that the runtime was unable to allocate sufficient memory.

Implementations

source

impl Trap

source

pub fn wasm(trap_code: TrapCode) -> Self

Construct a new Wasm trap with the given source location and trap code.

Internally saves a backtrace when constructed.

source

pub fn oom() -> Self

Construct a new OOM trap with the given source location and trap code.

Internally saves a backtrace when constructed.
