Struct wasm_encoder::MemorySection

pub struct MemorySection { /* private fields */ }

An encoder for the memory section.

Memory sections are only supported for modules.

Example

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

let mut memories = MemorySection::new();
memories.memory(MemoryType {
    minimum: 1,
    maximum: None,
    memory64: false,
    shared: false,
    page_size_log2: None,
});

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

let wasm_bytes = module.finish();

Implementations
