Struct kythera_fvm::SyscallError

source · 
pub struct SyscallError(pub String, pub ErrorNumber);
Expand description

Represents an error from a syscall. It can optionally contain a syscall-advised exit code for the kind of error that was raised. We may want to add an optional source error here.

Automatic conversions from String are provided, with no advised exit code.
