Struct wasm_encoder::ImportSection

pub struct ImportSection { /* private fields */ }

An encoder for the import section of WebAssembly modules.

Example

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

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

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

let bytes = module.finish();

Implementations

impl ImportSection

pub fn new() -> Self

pub fn import(
    &mut self,
    module: &str,
    field: &str,
    ty: impl Into<EntityType>
) -> &mut Self
