Struct wasm_encoder::NameSection

pub struct NameSection { /* fields omitted */ }

An encoder for the custom name section.

Example

use wasm_encoder::{Module, NameSection, NameMap};

let mut names = NameSection::new();
names.module("the module name");

let mut function_names = NameMap::new();
function_names.append(0, "name of function 0");
function_names.append(1, "a better function");
function_names.append(3, "the best function");
names.functions(&function_names);

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

let wasm_bytes = module.finish();

Implementations

impl NameSection

pub fn new() -> Self

Creates a new blank name custom section.

pub fn module(&mut self, name: &str)

Appends a module name subsection to this section.

This will indicate that the name of the entire module should be the name specified. Note that this should be encoded first before other subsections.

pub fn functions(&mut self, names: &NameMap)

Appends a subsection for the names of all functions in this wasm module.

Function names are declared in the names map provided where the index in the map corresponds to the wasm index of the function. This section should come after the module name subsection (if present) and before the locals subsection (if present).

pub fn locals(&mut self, names: &IndirectNameMap)

Appends a subsection for the names of locals within functions in the wasm module.

This section should come after the function name subsection (if present) and before the labels subsection (if present).

pub fn labels(&mut self, names: &IndirectNameMap)

Appends a subsection for the names of labels within functions in the wasm module.

This section should come after the local name subsection (if present) and before the type subsection (if present).

pub fn types(&mut self, names: &NameMap)

Appends a subsection for the names of all types in this wasm module.

This section should come after the label name subsection (if present) and before the table subsection (if present).

pub fn tables(&mut self, names: &NameMap)

Appends a subsection for the names of all tables in this wasm module.

This section should come after the type name subsection (if present) and before the memory subsection (if present).

pub fn memories(&mut self, names: &NameMap)

Appends a subsection for the names of all memories in this wasm module.

This section should come after the table name subsection (if present) and before the global subsection (if present).

pub fn globals(&mut self, names: &NameMap)

Appends a subsection for the names of all globals in this wasm module.

This section should come after the memory name subsection (if present) and before the element subsection (if present).

pub fn elements(&mut self, names: &NameMap)

Appends a subsection for the names of all elements in this wasm module.

This section should come after the global name subsection (if present) and before the data subsection (if present).

pub fn data(&mut self, names: &NameMap)

Appends a subsection for the names of all data in this wasm module.

This section should come after the element name subsection (if present).
