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

version: Option<u16>

The version of the WebAssembly module.

start_func: Option<FuncAddr>

The start function of the WebAssembly module.

funcs: Box<[TypedWasmFunction]>

The functions of the WebAssembly module.

func_types: Box<[FuncType]>

The types of the WebAssembly module.

exports: Box<[Export]>

The exports of the WebAssembly module.

globals: Box<[Global]>

The tables of the WebAssembly module.

table_types: Box<[TableType]>

The tables of the WebAssembly module.

memory_types: Box<[MemoryType]>

The memories of the WebAssembly module.

imports: Box<[Import]>

The imports of the WebAssembly module.

data: Box<[Data]>

Data segments of the WebAssembly module.

elements: Box<[Element]>

Element segments of the WebAssembly module.

Implementations

impl TinyWasmModule

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

Creates a TinyWasmModule from a slice of bytes.

pub unsafe fn from_twasm_unchecked(wasm: &[u8]) -> Self

Creates a TinyWasmModule from a slice of bytes.

Safety

This function is only safe to call if the bytes have been created by a trusted source. Otherwise, it may cause undefined behavior.

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<u16>: Archive, Option<FuncAddr>: Archive, Box<[TypedWasmFunction]>: 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<u16>: Archive, Archived<Option<u16>>: Deserialize<Option<u16>, __D>, Option<FuncAddr>: Archive, Archived<Option<FuncAddr>>: Deserialize<Option<FuncAddr>, __D>, Box<[TypedWasmFunction]>: Archive, Archived<Box<[TypedWasmFunction]>>: Deserialize<Box<[TypedWasmFunction]>, __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

This method tests for self and other values to be equal, and is used by ==.

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

This method 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<u16>: Serialize<__S>, Option<FuncAddr>: Serialize<__S>, Box<[TypedWasmFunction]>: 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.
