[][src]Struct wasmi::StackRecycler

pub struct StackRecycler { /* fields omitted */ }

Used to recycle stacks instead of allocating them repeatedly.

Implementations

impl StackRecycler[src]

pub fn with_limits(value_stack_limit: usize, call_stack_limit: usize) -> Self[src]

Limit stacks created by this recycler to

  • value_stack_limit bytes for values and
  • call_stack_limit levels for calls.

pub fn clear(&mut self)[src]

Clears any values left on the stack to avoid leaking them to future export invocations.

This is a secondary defense to prevent modules from exploiting faulty stack handling in the interpreter.

Do note that there are additional channels that can leak information into an untrusted module.
