Struct wasmer_runtime::Table

pub struct Table { /* fields omitted */ }

Container with a descriptor and a reference to a table storage.

Implementations

impl Table

pub fn new(
    descriptor: TableType,
    initial_value: Value<Function>
) -> Result<Table, RuntimeError>

Create a new Table from a TableDescriptor

Usage

let descriptor = TableDescriptor {
    ty: Type::ExternRef,
    minimum: 10,
    maximum: None,
};

let table = Table::new(descriptor, Value::null())?;

pub fn descriptor(&self) -> TableType

Get the TableDescriptor used to create this Table.

pub fn set(
    &self,
    index: u32,
    value: Value<Function>
) -> Result<(), RuntimeError>

Set the element at index.

pub fn get(&self, index: u32) -> Option<Value<Function>>

pub fn size(&self) -> u32

The current size of this table.

pub fn grow(
    &self,
    delta: u32,
    initial_value: Value<Function>
) -> Result<u32, RuntimeError>

Grow this table by delta.

Trait Implementations

impl Clone for Table

fn clone(&self) -> Table

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Exportable<'a> for Table

fn to_export(&self) -> Export

This function is used when providedd the [Extern] as exportable, so it can be used while instantiating the [Module].

fn get_self_from_extern(r#extern: &'a Extern) -> Result<&'a Table, ExportError>

Implementation of how to get the export corresponding to the implementing type from an [Instance] by name.

impl<'_> From<&'_ Table> for Table

fn from(new_table: &Table) -> Table

Performs the conversion.
