Trait for implementing the interface of a Wasm table.

Required methods

fn style(&self) -> &TableStyle

Returns the style for this Table.

fn ty(&self) -> &TableType

Returns the type for this Table.

fn size(&self) -> u32

Returns the number of allocated elements.

fn grow(&self, delta: u32) -> Option<u32>

Grow table by the specified amount of elements.

Returns None if table can't be grown by the specified amount of elements, otherwise returns the previous size of the table.

fn get(&self, index: u32) -> Option<VMCallerCheckedAnyfunc>

Get reference to the specified element.

Returns None if the index is out of bounds.

fn set(&self, index: u32, func: VMCallerCheckedAnyfunc) -> Result<(), Trap>

Set reference to the specified element.

Errors

Returns an error if the index is out of bounds.

fn vmtable(&self) -> NonNull<VMTableDefinition>

Return a VMTableDefinition for exposing the table to compiled wasm code.

Provided methods

fn copy(
    &self,
    src_table: &dyn Table,
    dst_index: u32,
    src_index: u32,
    len: u32
) -> Result<(), Trap>

Copy len elements from src_table[src_index..] into dst_table[dst_index..].

Errors
