Struct Table 

pub struct Table(/* private fields */);

Newtype wrapper around wasmer::Table.

Implementations

impl Table

pub fn new(inner: Table) -> Self

Create a wasm_runtime_layer::Table-compatible Table from a wasmer::Table.

pub fn into_inner(self) -> Table

Consume a Table to obtain the inner wasmer::Table.

Methods from Deref<Target = Table>

pub fn as_sys(&self) -> &Table

Convert a reference to self into a reference crate::backend::sys::table::Table.

pub fn as_sys_mut(&mut self) -> &mut Table

Convert a mutable reference to self into a mutable reference crate::backend::sys::table::Table.

pub fn ty(&self, store: &impl AsStoreRef) -> TableType

Returns the TableType of the table.

pub fn get(&self, store: &mut impl AsStoreMut, index: u32) -> Option<Value>

Retrieves an element of the table at the provided index.

pub fn set( &self, store: &mut impl AsStoreMut, index: u32, val: Value, ) -> Result<(), RuntimeError>

Sets an element val in the Table at the provided index.

pub fn size(&self, store: &impl AsStoreRef) -> u32

Retrieves the size of the Table (in elements)

pub fn grow( &self, store: &mut impl AsStoreMut, delta: u32, init: Value, ) -> Result<u32, RuntimeError>

Grows the size of the Table by delta, initializating the elements with the provided init value.

It returns the previous size of the Table in case is able to grow the Table successfully.

Errors

Returns an error if the delta is out of bounds for the table.

pub fn is_from_store(&self, store: &impl AsStoreRef) -> bool

Checks whether this Table can be used with the given context.

Trait Implementations

impl AsMut<Table> for Table

fn as_mut(&mut self) -> &mut Table

Converts this type into a mutable reference of the (usually inferred) input type.

impl AsMut<Table> for Table

fn as_mut(&mut self) -> &mut Table

Converts this type into a mutable reference of the (usually inferred) input type.

impl AsRef<Table> for Table

fn as_ref(&self) -> &Table

Converts this type into a shared reference of the (usually inferred) input type.

impl AsRef<Table> for Table

fn as_ref(&self) -> &Table

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Table

fn clone(&self) -> Table

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Deref for Table

type Target = Table

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for Table

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl From<Table> for Table

fn from(inner: Table) -> Self

Converts to this type from the input type.

impl From<Table> for Table

fn from(wrapper: Table) -> Self

Converts to this type from the input type.

impl WasmTable<Engine> for Table

fn new( ctx: impl AsContextMut<Engine>, ty: TableType, init: Value<Engine>, ) -> Result<Self>

Creates a new table to the store.

fn ty(&self, ctx: impl AsContext<Engine>) -> TableType

Returns the type and limits of the table.

fn size(&self, ctx: impl AsContext<Engine>) -> u32

Returns the current size of the table.

fn grow( &self, ctx: impl AsContextMut<Engine>, delta: u32, init: Value<Engine>, ) -> Result<u32>

Grows the table by the given amount of elements.

fn get( &self, ctx: impl AsContextMut<Engine>, index: u32, ) -> Option<Value<Engine>>

Returns the table element value at index.

fn set( &self, ctx: impl AsContextMut<Engine>, index: u32, value: Value<Engine>, ) -> Result<()>

Sets the value of this table at index.
