Struct wasmer_types::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>) -> Self

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 version of this type.

type Resolver = TableTypeResolver

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

fn resolve(
    &self,
    pos: usize,
    resolver: Self::Resolver,
    out: &mut MaybeUninit<Self::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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TableType

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

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

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

Deserializes using the given deserializer

impl Display for TableType

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

Formats the value using the given formatter.

impl Hash for TableType

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, 

Feeds a slice of this type into the given Hasher.

impl MemoryUsage for TableType

fn size_of_val(&self, visited: &mut dyn MemoryUsageTracker) -> usize

Returns the size of the referenced value in bytes.

impl PartialEq<TableType> for TableType

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &TableType) -> bool

This method tests for !=.

impl Serialize for TableType

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.

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

fn serialize(&self, serializer: &mut __S) -> Result<Self::Resolver, __S::Error>

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