Struct wasmi::StackRecycler[−][src]

pub struct StackRecycler { /* fields omitted */ }
Expand description

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.

Trait Implementations

impl Default for StackRecycler[src]

fn default() -> Self[src]

Returns the “default value” for a type. Read more

Blanket Implementations

impl<T> Any for T where
    T: 'static + ?Sized, [src]

pub fn type_id(&self) -> TypeId[src]

Gets the TypeId of self. Read more

impl<T> Borrow<T> for T where
    T: ?Sized, [src]

pub fn borrow(&self) -> &T[src]

Immutably borrows from an owned value. Read more

impl<T> BorrowMut<T> for T where
    T: ?Sized, [src]

pub fn borrow_mut(&mut self) -> &mut T[src]

Mutably borrows from an owned value. Read more

impl<T> Downcast for T where
    T: Any, [src]

pub fn into_any(self: Box<T, Global>) -> Box<dyn Any + 'static, Global>[src]

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait. Read more

pub fn into_any_rc(self: Rc<T>) -> Rc<dyn Any + 'static>[src]

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait. Read more

pub fn as_any(&self) -> &(dyn Any + 'static)[src]

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s. Read more

pub fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)[src]

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s. Read more

impl<T> From<T> for T[src]

pub fn from(t: T) -> T[src]

Performs the conversion.

impl<T, U> Into<U> for T where
    U: From<T>, [src]

pub fn into(self) -> U[src]

Performs the conversion.

impl<T, U> TryFrom<U> for T where
    U: Into<T>, [src]

type Error = Infallible

The type returned in the event of a conversion error.

pub fn try_from(value: U) -> Result<T, <T as TryFrom<U>>::Error>[src]

Performs the conversion.

impl<T, U> TryInto<U> for T where
    U: TryFrom<T>, [src]

type Error = <U as TryFrom<T>>::Error

The type returned in the event of a conversion error.

pub fn try_into(self) -> Result<U, <U as TryFrom<T>>::Error>[src]

Performs the conversion.
