pub struct ComponentImportSection { /* private fields */ }
Expand description

An encoder for the import section of WebAssembly components.

Example

use wasm_encoder::{Component, ComponentTypeSection, PrimitiveValType, ComponentImportSection, ComponentTypeRef};

let mut types = ComponentTypeSection::new();

// Define a function type of `[string, string] -> string`.
types
  .function()
  .params(
    [
      ("a", PrimitiveValType::String),
      ("b", PrimitiveValType::String)
    ]
  )
  .result(PrimitiveValType::String);

// This imports a function named `f` with the type defined above
let mut imports = ComponentImportSection::new();
imports.import("f", ComponentTypeRef::Func(0));

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

let bytes = component.finish();

Implementations

Create a new component import section encoder.

The number of imports in the section.

Determines if the section is empty.

Define an import in the component import section.
