Struct substrate_test_runtime_client::sc_executor::wasmi::FuncInvocation [−]
pub struct FuncInvocation<'args> { /* fields omitted */ }
Expand description
A resumable invocation handle. This struct is returned by FuncInstance::invoke_resumable
.
Implementations
impl<'args> FuncInvocation<'args>
impl<'args> FuncInvocation<'args>
pub fn is_resumable(&self) -> bool
pub fn is_resumable(&self) -> bool
Whether this invocation is currently resumable.
pub 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.
pub fn start_execution<'externals, E>(
&mut self,
externals: &'externals mut E
) -> Result<Option<RuntimeValue>, ResumableError> where
E: 'externals + Externals,
pub fn start_execution<'externals, E>(
&mut self,
externals: &'externals mut E
) -> Result<Option<RuntimeValue>, ResumableError> where
E: 'externals + Externals,
Start the invocation execution.
pub fn resume_execution<'externals, E>(
&mut self,
return_val: Option<RuntimeValue>,
externals: &'externals mut E
) -> Result<Option<RuntimeValue>, ResumableError> where
E: 'externals + Externals,
pub fn resume_execution<'externals, E>(
&mut self,
return_val: Option<RuntimeValue>,
externals: &'externals mut E
) -> Result<Option<RuntimeValue>, ResumableError> where
E: 'externals + Externals,
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.

pub fn is_in_subset(&self) -> bool
pub fn is_in_subset(&self) -> bool
Checks if self
is actually part of its subset T
(and can be converted to it).
pub fn to_subset_unchecked(&self) -> SS
pub fn to_subset_unchecked(&self) -> SS
Use with care! Same as self.to_subset
but without any property checks. Always succeeds.
pub fn from_subset(element: &SS) -> SP
pub fn from_subset(element: &SS) -> SP
The inclusion map: converts self
to the equivalent element of its superset.
The counterpart to unchecked_from
.
Consume self to return an equivalent value of T
.
