Struct wasm_encoder::CoreTypeSection

pub struct CoreTypeSection { /* private fields */ }

An encoder for the core type section of WebAssembly components.

Example

use wasm_encoder::{Component, CoreTypeSection, ModuleType};

let mut types = CoreTypeSection::new();

types.module(&ModuleType::new());

let mut component = Component::new();
component.section(&types);

let bytes = component.finish();

Implementations

impl CoreTypeSection

pub fn new() -> Self

Create a new core type section encoder.

pub fn len(&self) -> u32

The number of types in the section.

pub fn is_empty(&self) -> bool

Determines if the section is empty.

pub fn ty(&mut self) -> CoreTypeEncoder<'_>

Encode a type into this section.

The returned encoder must be finished before adding another type.

pub fn function<P, R>(&mut self, params: P, results: R) -> &mut Self

where P: IntoIterator<Item = ValType>, P::IntoIter: ExactSizeIterator, R: IntoIterator<Item = ValType>, R::IntoIter: ExactSizeIterator,

Define a function type in this type section.

pub fn module(&mut self, ty: &ModuleType) -> &mut Self

Define a module type in this type section.

Currently this is only used for core type sections in components.

Trait Implementations

impl Clone for CoreTypeSection

fn clone(&self) -> CoreTypeSection

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ComponentSection for CoreTypeSection

fn id(&self) -> u8

Gets the section identifier for this section.

fn append_to_component(&self, dst: &mut Vec<u8>)

impl Debug for CoreTypeSection

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

Formats the value using the given formatter.

impl Default for CoreTypeSection

fn default() -> CoreTypeSection

Returns the “default value” for a type.

impl Encode for CoreTypeSection

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