Struct wasmtime::TableType

pub struct TableType { /* private fields */ }

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.

Implementations

impl TableType

pub fn new(element: RefType, min: u32, max: Option<u32>) -> TableType

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

pub fn element(&self) -> &RefType

Returns the element value type of this table.

pub fn minimum(&self) -> u32

Returns minimum number of elements this table must have

pub fn maximum(&self) -> Option<u32>

Returns the optionally-specified maximum number of elements this table can have.

If this returns None then the table is not limited in size.

Trait Implementations

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.
