Function wasmtime_runtime::raise_user_trap

pub unsafe fn raise_user_trap(error: Error, needs_backtrace: bool) -> !

Raises a user-defined trap immediately.

This function performs as-if a wasm trap was just executed, only the trap has a dynamic payload associated with it which is user-provided. This trap payload is then returned from catch_traps below.

Safety

Only safe to call when wasm code is on the stack, aka catch_traps must have been previously called. Additionally no Rust destructors can be on the stack. They will be skipped and not executed.
