Struct Table 

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

A Wasm table.

Implementations

impl Table

pub fn new( store: &mut Store, type_: TableType, val: Ref, ) -> Result<Self, TableError>

Creates a new Table with the given TableType and initialization Ref in the given Store.

Errors

• If the RefType of the initialization Ref does not match the RefType of the elements in the Table to be created.

Panics

• If the TableType is invalid.
• If the initialization Ref is not owned by the given Store.

pub fn type_(self, store: &Store) -> TableType

Returns the TableType of this Table.

pub fn get(self, store: &Store, idx: u32) -> Option<Ref>

Returns the element at the given index in this Table.

Errors

• If the access is out of bounds.

pub fn set( self, store: &mut Store, idx: u32, val: Ref, ) -> Result<(), TableError>

Sets the element at the given index in this Table to the given Ref.

Errors

• If the access is out of bounds.
• If the RefType of the given Ref does not match the RefType of the elements in this Table.

Panics

• If the given Ref is not owned by the given Store.

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

Returns the size of this Table in number of elements.

pub fn grow( self, store: &mut Store, val: Ref, count: u32, ) -> Result<(), TableError>

Grows this Table by the given number of elements with the given initialization Ref.

Returns the previous size of this Table in number of elements.

Errors

• If the RefType of the given initialization Ref does not match the RefType of the elements in this Table.
• If this Table failed to grow.

Panics

• If the given initialization Ref is not owned by the given Store.

Trait Implementations

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 Debug for Table

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

Formats the value using the given formatter.

impl From<Table> for ExternVal

fn from(table: Table) -> Self

Converts to this type from the input type.

impl Hash for Table

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Table

fn eq(&self, other: &Table) -> 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.
