Struct wasm_encoder::component::AdapterFunctionSection

pub struct AdapterFunctionSection { /* fields omitted */ }

An encoder for the component adapter function section.

Example

use wasm_encoder::component::{Component, AdapterFunctionSection, CanonicalOption};

// This assumes there is an adapter function type with
// index 0 and a target function with index 0.
let mut adapters = AdapterFunctionSection::new();
adapters.adapter(0, &[CanonicalOption::UTF8], 0);

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

let bytes = component.finish();

Implementations

impl AdapterFunctionSection

pub fn new() -> Self

Create a new component adapter function section encoder.

pub fn len(&self) -> u32

The number of adapter functions in the section.

pub fn is_empty(&self) -> bool

Determines if the section is empty.

pub fn adapter(
    &mut self,
    type_index: u32,
    options: &[CanonicalOption],
    target_index: u32
) -> &mut Self

Define an adapter function in the adapter function section.

type_index must be to an adapter function type. target_index must be to a function.
