Provides a Wasm table reference.

Required Methods

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

Creates a new table to the store.

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

Returns the type and limits of the table.

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

Returns the current size of the table.

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

Grows the table by the given amount of elements.

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

Returns the table element value at index.

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

Sets the value of this table at index.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
