Struct wasmi::TableInstance

pub struct TableInstance { /* fields omitted */ }

Runtime representation of a table.

A table is a array of untyped functions. It allows wasm code to call functions indirectly through a dynamic index into a table. For example, this allows emulating function pointers by way of table indices.

Table is created with an initial size but can be grown dynamically via grow method. Growth can be limited by an optional maximum size.

In future, a table might be extended to be able to hold not only functions but different types.

Methods

impl TableInstance

fn alloc(
    initial_size: u32,
    maximum_size: Option<u32>
) -> Result<TableRef, Error>

fn initial_size(&self) -> u32

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

fn current_size(&self) -> u32

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

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

Get the specific value in the table

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

Set the table element to the specified function.

Trait Implementations

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
