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

Returns size this table was created with.

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

Returns maximum size TableInstance can grow to.

pub fn current_size(&self) -> u32

Returns current size of the table.

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.

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

Get the specific value in the table

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

Set the table element to the specified function.
