Struct Custom 

pub struct Custom { /* private fields */ }

Custom sections have the id 0. They are intended to be used for debugging information or third-party extensions, and are ignored by the WebAssembly semantics. Their contents consist of a name further identifying the custom section, followed by an uninterpreted sequence of bytes for custom use.

See https://webassembly.github.io/spec/core/binary/modules.html#binary-customsec

Examples

use wasm_ast::{Custom, Name};

let name = "version";
let version = b"1.0.0";
let custom = Custom::new(name.into(), version.to_vec());

assert_eq!(custom.name(), &Name::new(name.to_string()));
assert_eq!(custom.bytes(), &version[..]);

Implementations

impl Custom

pub fn new(name: Name, bytes: Vec<u8>) -> Self

Creates a new instance of a custom section.

pub fn name(&self) -> &Name

The name of the custom section.

pub fn bytes(&self) -> &[u8]

The contents of the custom section.

Trait Implementations

impl Clone for Custom

fn clone(&self) -> Custom

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Custom

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Custom

fn eq(&self, other: &Custom) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
