Struct Table 

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

Newtype wrapper around wasmi::Table.

Implementations

impl Table

pub fn new(inner: Table) -> Self

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

pub fn into_inner(self) -> Table

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

Methods from Deref<Target = Table>

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

Returns the type and limits of the table.

Panics

Panics if ctx does not own this Table.

pub fn size(&self, ctx: impl AsContext) -> u64

Returns the current size of the Table.

Panics

If ctx does not own this Table.

pub fn grow( &self, ctx: impl AsContextMut, delta: u64, init: Val, ) -> Result<u64, TableError>

Grows the table by the given amount of elements.

Returns the old size of the Table upon success.

Note

The newly added elements are initialized to the init Val.

Errors

• If the table is grown beyond its maximum limits.
• If value does not match the Table element type.

Panics

Panics if ctx does not own this Table.

pub fn get(&self, ctx: impl AsContext, index: u64) -> Option<Val>

Returns the Table element value at index.

Returns None if index is out of bounds.

Panics

Panics if ctx does not own this Table.

pub fn set( &self, ctx: impl AsContextMut, index: u64, value: Val, ) -> Result<(), TableError>

Sets the Val of this Table at index.

Errors

• If index is out of bounds.
• If value does not match the Table element type.

Panics

Panics if ctx does not own this Table.

pub fn fill( &self, ctx: impl AsContextMut, dst: u64, val: Val, len: u64, ) -> Result<(), TableError>

Fill table[dst..(dst + len)] with the given value.

Errors

• If val has a type mismatch with the element type of the Table.
• If the region to be filled is out of bounds for the Table.
• If val originates from a different Store than the Table.

Panics

If ctx does not own dst_table or src_table.

Trait Implementations

impl AsMut<Table> for Table

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