Struct wasmi::TableRef[−][src]

pub struct TableRef(_);
Expand description

Reference to a table (See TableInstance for details).

This reference has a reference-counting semantics.

Methods from Deref<Target = TableInstance>

pub fn initial_size(&self) -> u32[src]

Returns size this table was created with.

pub fn maximum_size(&self) -> Option<u32>[src]

Returns maximum size TableInstance can grow to.

pub fn current_size(&self) -> u32[src]

Returns current size of the table.

pub fn grow(&self, by: u32) -> Result<(), Error>[src]

Increases the size of the table by given number of elements.

Errors

Returns Err if tried to allocate more elements than permited by limit.

pub fn get(&self, offset: u32) -> Result<Option<FuncRef>, Error>[src]

Get the specific value in the table

pub fn set(&self, offset: u32, value: Option<FuncRef>) -> Result<(), Error>[src]

Set the table element to the specified function.

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> ToOwned for T where
    T: Clone, [src]

type Owned = T

The resulting type after obtaining ownership.

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

Creates owned data from borrowed data, usually by cloning. Read more

pub fn clone_into(&self, target: &mut T)[src]

🔬 This is a nightly-only experimental API. (toowned_clone_into)

recently added

Uses borrowed data to replace owned data, usually by cloning. Read more

    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.
