Struct 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,
        page_size_log2: None,
    }
);

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

let bytes = module.finish();

Implementations

impl ImportSection

pub fn new() -> Self

Create a new import section encoder.

pub fn len(&self) -> u32

The number of imports in the section.

pub fn is_empty(&self) -> bool

Determines if the section is empty.

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

Define an import in the import section.
