Struct wasm_encoder::ImportSection

pub struct ImportSection { /* private fields */ }

An encoder for the import section.

Example

use wasm_encoder::{Module, ImportSection, MemoryType};

let mut imports = ImportSection::new();
imports.import(
    "env",
    Some("memory"),
    MemoryType {
        minimum: 1,
        maximum: None,
        memory64: false,
    }
);

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

let wasm_bytes = module.finish();
