Struct Interpreter

pub struct Interpreter<'a> { /* private fields */ }

The Cranelift interpreter; this contains some high-level functions to control the interpreter’s flow. The interpreter state is defined separately (see InterpreterState) as the execution semantics for each Cranelift instruction (see step).

Implementations

impl<'a> Interpreter<'a>

pub fn new(state: InterpreterState<'a>) -> Self

pub fn with_fuel(self, fuel: Option<u64>) -> Self

The fuel mechanism sets a number of instructions that the interpreter can execute before stopping. If this value is None (the default), no limit is imposed.

pub fn call_by_name( &mut self, func_name: &str, arguments: &[DataValue], ) -> Result<ControlFlow<'a>, InterpreterError>

Call a function by name; this is a helpful proxy for Interpreter::call_by_index.

pub fn call_by_index( &mut self, index: FuncIndex, arguments: &[DataValue], ) -> Result<ControlFlow<'a>, InterpreterError>

Call a function by its index in the FunctionStore; this is a proxy for Interpreter::call.
