Struct wasm_encoder::TableSection

pub struct TableSection { /* private fields */ }

An encoder for the table section.

Table sections are only supported for modules.

Example

use wasm_encoder::{Module, TableSection, TableType, RefType};

let mut tables = TableSection::new();
tables.table(TableType {
    element_type: RefType::FUNCREF,
    minimum: 128,
    maximum: None,
});

let mut module = Module::new();
module.section(&tables);

let wasm_bytes = module.finish();

Implementations

impl TableSection

pub fn new() -> Self

Construct a new table section encoder.

pub fn len(&self) -> u32

The number of tables in the section.

pub fn is_empty(&self) -> bool

Determines if the section is empty.

pub fn table(&mut self, table_type: TableType) -> &mut Self

Define a table.

pub fn table_with_init( &mut self, table_type: TableType, init: &ConstExpr ) -> &mut Self

Define a table with an explicit initialization expression.

Note that this is part of the function-references proposal.

Trait Implementations

impl Default for TableSection

fn default() -> TableSection

Returns the “default value” for a type.

impl Encode for TableSection

fn encode(&self, sink: &mut Vec<u8>)

Encode the type into the given byte sink.

impl Section for TableSection
