Enum BackendTable 

pub enum BackendTable {
    Sys(Table),
}

Variants

Sys(Table)

The implementation from the sys backend.

Implementations

impl BackendTable

pub fn into_sys(self) -> Table

Consume self into crate::backend::sys::table::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.

impl BackendTable

pub fn unwrap_sys(self) -> Table

Unwraps this value to the BackendTable::Sys variant. Panics if this value is of any other type.

pub fn unwrap_sys_ref(&self) -> &Table

Unwraps this reference to the BackendTable::Sys variant. Panics if this value is of any other type.

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

Unwraps this mutable reference to the BackendTable::Sys variant. Panics if this value is of any other type.

impl BackendTable

pub fn new( store: &mut impl AsStoreMut, ty: TableType, init: Value, ) -> Result<Self, RuntimeError>

Creates a new table with the provided TableType definition.

All the elements in the table will be set to the init value.

This function will construct the table using the store BaseTunables.

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, initializing 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 copy( store: &mut impl AsStoreMut, dst_table: &Self, dst_index: u32, src_table: &Self, src_index: u32, len: u32, ) -> Result<(), RuntimeError>

Copies the len elements of src_table starting at src_index to the destination table dst_table at index dst_index.

Errors

Returns an error if the range is out of bounds of either the source or destination tables.

pub(crate) fn from_vm_extern( store: &mut impl AsStoreMut, ext: VMExternTable, ) -> Self

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

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

pub(crate) fn to_vm_extern(&self) -> VMExtern

Trait Implementations

impl Clone for BackendTable

fn clone(&self) -> BackendTable

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BackendTable

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

Formats the value using the given formatter.

impl From<BackendTable> for Table

fn from(value: BackendTable) -> Self

Converts to this type from the input type.

impl From<Table> for BackendTable

fn from(value: Table) -> Self

Converts to this type from the input type.

impl PartialEq for BackendTable

fn eq(&self, other: &BackendTable) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
