Struct wasm_encoder::ComponentFunctionSection

pub struct ComponentFunctionSection { /* private fields */ }

An encoder for the function section of WebAssembly components.

Example

use wasm_encoder::{Component, ComponentFunctionSection, CanonicalOption};

let mut functions = ComponentFunctionSection::new();
functions.lift(0, 0, [CanonicalOption::UTF8, CanonicalOption::Into(0)]);

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

let bytes = component.finish();

Implementations

impl ComponentFunctionSection

pub fn new() -> Self

Construct a new component function section encoder.

pub fn len(&self) -> u32

The number of functions in the section.

pub fn is_empty(&self) -> bool

Determines if the section is empty.

pub fn lift<O>(
    &mut self,
    type_index: u32,
    func_index: u32,
    options: O
) -> &mut Self where
    O: IntoIterator<Item = CanonicalOption>,
    O::IntoIter: ExactSizeIterator, 

Define a function that will lift a core WebAssembly function to the canonical interface ABI.

pub fn lower<O>(&mut self, func_index: u32, options: O) -> &mut Self where
    O: IntoIterator<Item = CanonicalOption>,
    O::IntoIter: ExactSizeIterator, 

Define a function that will lower a canonical interface ABI function to a core WebAssembly function.
