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

impl<'args> FuncInvocation<'args>
sourcepub fn is_resumable(&self) -> bool
pub fn is_resumable(&self) -> bool
Whether this invocation is currently resumable.
sourcepub fn resumable_value_type(&self) -> Option<ValueType>
pub fn resumable_value_type(&self) -> Option<ValueType>
If the invocation is resumable, the expected return value type to be feed back in.
sourcepub 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.
sourcepub 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.
