16//! A simple event-driven library for parsing WebAssembly binary files
17//! (or streams).
18//!
19//! The parser library reports events as they happen and only stores
20//! parsing information for a brief period of time, making it very fast
21//! and memory-efficient. The event-driven model, however, has some drawbacks.
22//! If you need random access to the entire WebAssembly data-structure,
23//! this is not the right library for you. You could however, build such
24//! a data-structure using this library.

35/// A helper macro to conveniently iterate over all opcodes recognized by this
36/// crate. This can be used to work with either the [`Operator`] enumeration or
37/// the [`VisitOperator`] trait if your use case uniformly handles all operators
38/// the same way.
39///
40/// It is also possible to specialize handling of operators depending on the
41/// Wasm proposal from which they are originating.
42///
43/// This is an "iterator macro" where this macro is invoked with the name of
44/// another macro, and then that macro is invoked with the list of all
45/// operators. An example invocation of this looks like:
46///
47/// The list of specializable Wasm proposals is as follows:
48///
49/// - `@mvp`: Denoting a Wasm operator from the initial Wasm MVP version.
50/// - `@exceptions`: [Wasm `expection-handling` proposal]
51/// - `@tail_call`: [Wasm `tail-calls` proposal]
52/// - `@reference_types`: [Wasm `reference-types` proposal]
53/// - `@sign_extension`: [Wasm `sign-extension-ops` proposal]
54/// - `@saturating_float_to_int`: [Wasm `non_trapping_float-to-int-conversions` proposal]
55/// - `@bulk_memory `:[Wasm `bulk-memory` proposal]
56/// - `@threads`: [Wasm `threads` proposal]
57/// - `@simd`: [Wasm `simd` proposal]
58/// - `@relaxed_simd`: [Wasm `relaxed-simd` proposal]
