[−][src]Struct wasmi::FuncInvocation
A resumable invocation handle. This struct is returned by FuncInstance::invoke_resumable
.
Implementations
impl<'args> FuncInvocation<'args>
[src][−]
pub fn is_resumable(&self) -> bool
[src][−]
Whether this invocation is currently resumable.
pub fn resumable_value_type(&self) -> Option<ValueType>
[src][−]
If the invocation is resumable, the expected return value type to be feed back in.
pub fn start_execution<'externals, E: Externals + 'externals>(
&mut self,
externals: &'externals mut E
) -> Result<Option<RuntimeValue>, ResumableError>
[src][−]
&mut self,
externals: &'externals mut E
) -> Result<Option<RuntimeValue>, ResumableError>
Start the invocation execution.
pub fn resume_execution<'externals, E: Externals + 'externals>(
&mut self,
return_val: Option<RuntimeValue>,
externals: &'externals mut E
) -> Result<Option<RuntimeValue>, ResumableError>
[src][−]
&mut self,
return_val: Option<RuntimeValue>,
externals: &'externals mut E
) -> Result<Option<RuntimeValue>, ResumableError>
Resume an execution if a previous trap of Host kind happened.
return_val
must be of the value type resumable_value_type
, defined by the host function import. Otherwise,
UnexpectedSignature
trap will be returned. The current invocation must also be resumable
is_resumable
. Otherwise, a NotResumable
error will be returned.
