Struct wasmi::FuncInvocation
source · [−]pub struct FuncInvocation<'args> { /* private fields */ }Expand description
A resumable invocation handle. This struct is returned by FuncInstance::invoke_resumable.
Implementations
Whether this invocation is currently resumable.
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>
pub fn start_execution<'externals, E: Externals + 'externals>(
&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>
pub fn resume_execution<'externals, E: Externals + 'externals>(
&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.
