Struct wasmi::TableRef

source ·
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>§

source

pub fn initial_size(&self) -> u32

Returns size this table was created with.

source

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

Returns maximum size TableInstance can grow to.

source

pub fn current_size(&self) -> u32

Returns current size of the table.

source

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

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

Errors

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

source

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

Get the specific value in the table

source

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

Set the table element to the specified function.

impl<T> Downcast for Twhere T: Any,

source§

fn into_any(self: Box<T, Global>) -> Box<dyn Any, Global>

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.
source§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

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

fn as_any(&self) -> &(dyn Any + 'static)

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

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

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