Lucet runtime errors.

Variants§

§

InvalidArgument(&'static str)

§

RegionFull(usize)

A Region cannot currently accommodate additional instances.

§

ModuleError(ModuleError)

A module error occurred.

§

LimitsExceeded(String)

A method call or module specification would exceed an instance’s Limits.

§

NoLinearMemory(String)

A method call attempted to modify linear memory for an instance that does not have linear memory

§

SymbolNotFound(String)

An attempt to look up a WebAssembly function by its symbol name failed.

§

FuncNotFound(u32, u32)

An attempt to look up a WebAssembly function by its table index failed.

§

RuntimeFault(FaultDetails)

An instance aborted due to a runtime fault.

§

RuntimeTerminated(TerminationDetails)

An instance terminated, potentially with extra information about the termination.

This condition can arise from a hostcall explicitly calling Vmctx::terminate(), or via a custom signal handler that returns SignalBehavior::Terminate.

§

DlError(Error)

IO errors arising during dynamic loading with DlModule.

§

InstanceNotReturned

§

InstanceNotYielded

§

StartYielded

§

InternalError(Error)

A catch-all for internal errors that are likely unrecoverable by the runtime user.

As the API matures, these will likely become rarer, replaced by new variants of this enum, or by panics for truly unrecoverable situations.

§

Unsupported(String)

An unsupported feature was used.
