Enum hdk::prelude::WasmError [−]
Enum of all possible ERROR codes that a Zome API Function could return.
Variants
while converting pointers and lengths between u64 and i64 across the host/guest we hit either a negative number (cannot fit in u64) or very large number (cannot fit in i64) negative pointers and lengths are almost certainly indicative of a critical bug somewhere max i64 represents about 9.2 exabytes so should keep us going long enough to patch wasmer if commercial hardware ever threatens to overstep this limit
These bytes failed to deserialize. The host should provide nice debug info and context that the wasm guest won’t have.
Serialize(SerializedBytesError)
Something failed to serialize. This should be rare or impossible for basically everything that implements Serialize.
Somehow we errored while erroring. For example, maybe we failed to serialize an error while attempting to serialize an error.
Something went wrong while writing or reading bytes to/from wasm memory. this means something like “reading 16 bytes did not produce 2x WasmSize ints” or maybe even “failed to write a byte to some pre-allocated wasm memory” whatever this is it is very bad and probably not recoverable
GuestResultHandling(String)
Failed to take bytes out of the guest and do something with it. The string is whatever error message comes back from the interal process.
Guest(String)
Something to do with guest logic that we don’t know about
Host(String)
Something to do with host logic that we don’t know about
Compile(String)
Somehow wasmer failed to compile machine code from wasm byte code
CallError(String)
