Struct wasmi::FuncInvocation[−][src]

pub struct FuncInvocation<'args> { /* fields omitted */ }

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]

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]

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.
