Expand description

Stores trace message with backtrace.

Variants

User(Box<dyn Error + Send + Sync>)

A user-raised trap through raise_user_trap.

Wasm

A trap raised from the Wasm generated code

Note: this trap is deterministic (assuming a deterministic host implementation)

Show fields

Fields of Wasm

pc: usize

The program counter in generated code where this trap happened.

backtrace: Backtrace

Native stack backtrace at the time the trap occurred

signal_trap: Option<TrapCode>

Optional trapcode associated to the signal that caused the trap

Lib

A trap raised from a wasm libcall

Note: this trap is deterministic (assuming a deterministic host implementation)

Show fields

Fields of Lib

trap_code: TrapCode

Code of the trap.

backtrace: Backtrace

Native stack backtrace at the time the trap occurred

OOM

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

Note: this trap is nondeterministic, since it depends on the host system.

Show fields

Fields of OOM

backtrace: Backtrace

Native stack backtrace at the time the OOM occurred

Implementations

impl Trap[src]

pub fn wasm(
    pc: usize,
    backtrace: Backtrace,
    signal_trap: Option<TrapCode>
) -> Self[src]

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

Internally saves a backtrace when constructed.

pub fn lib(trap_code: TrapCode) -> Self[src]

Construct a new Wasm trap with the given trap code.

Internally saves a backtrace when constructed.

pub fn oom() -> Self[src]

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

Internally saves a backtrace when constructed.
