Struct wasm_encoder::DataSection
source · pub struct DataSection { /* private fields */ }
Expand description
An encoder for the data section.
Data sections are only supported for modules.
§Example
use wasm_encoder::{
ConstExpr, DataSection, Instruction, MemorySection, MemoryType,
Module,
};
let mut memory = MemorySection::new();
memory.memory(MemoryType {
minimum: 1,
maximum: None,
memory64: false,
shared: false,
page_size_log2: None,
});
let mut data = DataSection::new();
let memory_index = 0;
let offset = ConstExpr::i32_const(42);
let segment_data = b"hello";
data.active(memory_index, &offset, segment_data.iter().copied());
let mut module = Module::new();
module
.section(&memory)
.section(&data);
let wasm_bytes = module.finish();
