Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
BufferLengthError
Thrown by hostcalls when a buffer is larger than its *_len
limit.
FatalError(String)
Error when viceroy has encountered a fatal error and the underlying wasmtime instance must be terminated with a Trap.
FileFormat
Error when viceroy has been given an invalid file.
ProfilingStrategy
FastlyConfig(FastlyConfigError)
BackendUrl(Url)
GuestError(GuestError)
An error from guest-provided arguments to a hostcall. These errors may be created
automatically by the Wiggle-generated glue code that converts parameters from their ABI
representation into richer Rust types, or by fallible methods of GuestPtr
in the
wiggle_abi trait implementations.
HandleError(HandleError)
HyperError(Error)
Infallible(Infallible)
InvalidArgument
Error when an invalid argument is supplied to a hostcall.
InvalidHeaderName(InvalidHeaderName)

InvalidUri(InvalidUri)
