Struct TableType

pub struct TableType {
    pub ty: Type,
    pub minimum: u32,
    pub maximum: Option<u32>,
}

A descriptor for a table in a WebAssembly module.

Tables are contiguous chunks of a specific element, typically a funcref or an externref. The most common use for tables is a function table through which call_indirect can invoke other functions.

Fields

ty: Type

The type of data stored in elements of the table.

minimum: u32

The minimum number of elements in the table.

maximum: Option<u32>

The maximum number of elements in the table.

Implementations

impl TableType

pub fn new(ty: Type, minimum: u32, maximum: Option<u32>) -> TableType

Creates a new table descriptor which will contain the specified element and have the limits applied to its length.

Trait Implementations

impl Archive for TableType

where Type: Archive, u32: Archive, Option<u32>: Archive,

type Archived = ArchivedTableType

The archived representation of this type.

type Resolver = TableTypeResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

unsafe fn resolve( &self, pos: usize, resolver: <TableType as Archive>::Resolver, out: *mut <TableType as Archive>::Archived, )

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for TableType

fn clone(&self) -> TableType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TableType

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

Formats the value using the given formatter.

impl<__D> Deserialize<TableType, __D> for <TableType as Archive>::Archived

where __D: Fallible + ?Sized, Type: Archive, <Type as Archive>::Archived: Deserialize<Type, __D>, u32: Archive, <u32 as Archive>::Archived: Deserialize<u32, __D>, Option<u32>: Archive, <Option<u32> as Archive>::Archived: Deserialize<Option<u32>, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<TableType, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl Display for TableType

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

Formats the value using the given formatter.

impl Hash for TableType

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

where __H: Hasher,

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 TableType

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

impl<__S> Serialize<__S> for TableType

where __S: Fallible + ?Sized, Type: Serialize<__S>, u32: Serialize<__S>, Option<u32>: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<TableType as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.
