A TinyWasm WebAssembly Module

This is the internal representation of a WebAssembly module in TinyWasm. TinyWasmModules are validated before being created, so they are guaranteed to be valid (as long as they were created by TinyWasm). This means you should not trust a TinyWasmModule created by a third party to be valid.

Fields

start_func: Option<FuncAddr>

Optional address of the start function

Corresponds to the start section of the original WebAssembly module.

funcs: Box<[WasmFunction]>

Optimized and validated WebAssembly functions

Contains data from to the code, func, and type sections of the original WebAssembly module.

func_types: Box<[FuncType]>

A vector of type definitions, indexed by TypeAddr

Corresponds to the type section of the original WebAssembly module.

exports: Box<[Export]>

Exported items of the WebAssembly module.

Corresponds to the export section of the original WebAssembly module.

globals: Box<[Global]>

Global components of the WebAssembly module.

Corresponds to the global section of the original WebAssembly module.

table_types: Box<[TableType]>

Table components of the WebAssembly module used to initialize tables.

Corresponds to the table section of the original WebAssembly module.

memory_types: Box<[MemoryType]>

Memory components of the WebAssembly module used to initialize memories.

Corresponds to the memory section of the original WebAssembly module.

imports: Box<[Import]>

Imports of the WebAssembly module.

Corresponds to the import section of the original WebAssembly module.

data: Box<[Data]>

Data segments of the WebAssembly module.

Corresponds to the data section of the original WebAssembly module.

elements: Box<[Element]>

Element segments of the WebAssembly module.

Corresponds to the elem section of the original WebAssembly module.

Implementations

impl TinyWasmModule

pub fn from_twasm(wasm: &[u8]) -> Result<TinyWasmModule, TwasmError>

Creates a TinyWasmModule from a slice of bytes.

pub fn serialize_twasm(&self) -> AlignedVec

Serializes the TinyWasmModule into a vector of bytes. AlignedVec can be deferenced as a slice of bytes and implements io::Write when the std feature is enabled.

Trait Implementations

impl Archive for TinyWasmModule

where Option<FuncAddr>: Archive, Box<[WasmFunction]>: Archive, Box<[FuncType]>: Archive, Box<[Export]>: Archive, Box<[Global]>: Archive, Box<[TableType]>: Archive, Box<[MemoryType]>: Archive, Box<[Import]>: Archive, Box<[Data]>: Archive, Box<[Element]>: Archive,

type Archived = ArchivedTinyWasmModule

The archived representation of this type.

type Resolver = TinyWasmModuleResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

unsafe fn resolve( &self, pos: usize, resolver: Self::Resolver, out: *mut Self::Archived, )

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for TinyWasmModule

fn clone(&self) -> TinyWasmModule

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TinyWasmModule

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

Formats the value using the given formatter.

impl Default for TinyWasmModule

fn default() -> TinyWasmModule

Returns the “default value” for a type.

impl<__D: Fallible + ?Sized> Deserialize<TinyWasmModule, __D> for Archived<TinyWasmModule>

where Option<FuncAddr>: Archive, Archived<Option<FuncAddr>>: Deserialize<Option<FuncAddr>, __D>, Box<[WasmFunction]>: Archive, Archived<Box<[WasmFunction]>>: Deserialize<Box<[WasmFunction]>, __D>, Box<[FuncType]>: Archive, Archived<Box<[FuncType]>>: Deserialize<Box<[FuncType]>, __D>, Box<[Export]>: Archive, Archived<Box<[Export]>>: Deserialize<Box<[Export]>, __D>, Box<[Global]>: Archive, Archived<Box<[Global]>>: Deserialize<Box<[Global]>, __D>, Box<[TableType]>: Archive, Archived<Box<[TableType]>>: Deserialize<Box<[TableType]>, __D>, Box<[MemoryType]>: Archive, Archived<Box<[MemoryType]>>: Deserialize<Box<[MemoryType]>, __D>, Box<[Import]>: Archive, Archived<Box<[Import]>>: Deserialize<Box<[Import]>, __D>, Box<[Data]>: Archive, Archived<Box<[Data]>>: Deserialize<Box<[Data]>, __D>, Box<[Element]>: Archive, Archived<Box<[Element]>>: Deserialize<Box<[Element]>, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<TinyWasmModule, __D::Error>

Deserializes using the given deserializer

impl PartialEq for TinyWasmModule

fn eq(&self, other: &TinyWasmModule) -> 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.

impl<__S: Fallible + ?Sized> Serialize<__S> for TinyWasmModule

where Option<FuncAddr>: Serialize<__S>, Box<[WasmFunction]>: Serialize<__S>, Box<[FuncType]>: Serialize<__S>, Box<[Export]>: Serialize<__S>, Box<[Global]>: Serialize<__S>, Box<[TableType]>: Serialize<__S>, Box<[MemoryType]>: Serialize<__S>, Box<[Import]>: Serialize<__S>, Box<[Data]>: Serialize<__S>, Box<[Element]>: Serialize<__S>,

fn serialize(&self, serializer: &mut __S) -> Result<Self::Resolver, __S::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.
