Expand description
A runtime-independent way for Wiggle to terminate WebAssembly execution.
Functions that are marked (@witx noreturn)
will always return a Trap.
Other functions that want to Trap can do so via their UserErrorConversion
trait, which transforms the user’s own error type into a Result<abierror, Trap>
.
Variants
I32Exit(i32)
A Trap which indicates an i32 (posix-style) exit code. Runtimes may have a special way of dealing with this for WASI embeddings and otherwise.
String(String)
Any other Trap is just an unstructured String, for reporting and debugging.
