The WebAssembly.CompileError
object indicates an error during WebAssembly decoding or validation.
A WebAssembly.Global
object represents a global variable instance, accessible from
both JavaScript and importable/exportable across one or more WebAssembly.Module
instances. This allows dynamic linking of multiple modules.
A WebAssembly.Instance
object is a stateful, executable instance of a WebAssembly.Module
.
Instance objects contain all the Exported WebAssembly functions that allow calling into
WebAssembly code from JavaScript.
The WebAssembly.LinkError
object indicates an error during module instantiation
(besides traps from the start function).
The WebAssembly.Memory
object is a resizable ArrayBuffer
or SharedArrayBuffer
that
holds the raw bytes of memory accessed by a WebAssembly Instance.
A WebAssembly.Module
object contains stateless WebAssembly code that has already been compiled
by the browser — this can be efficiently shared with Workers, and instantiated multiple times.
The WebAssembly.RuntimeError
object is the error type that is thrown whenever WebAssembly
specifies a trap.
The WebAssembly.Table()
object is a JavaScript wrapper object — an array-like structure
representing a WebAssembly Table, which stores function references. A table created by
JavaScript or in WebAssembly code will be accessible and mutable from both JavaScript
and WebAssembly.
The WebAssembly.compile()
function compiles WebAssembly binary code into a
WebAssembly.Module
object. This function is useful if it is necessary to compile
a module before it can be instantiated (otherwise, the WebAssembly.instantiate()
function should be used).
The WebAssembly.compileStreaming()
function compiles a WebAssembly.Module
directly from a streamed underlying source. This function is useful if it is
necessary to a compile a module before it can be instantiated (otherwise, the
WebAssembly.instantiateStreaming()
function should be used).
The WebAssembly.instantiate() function allows you to compile and instantiate WebAssembly code.
The WebAssembly.instantiateStreaming()
function compiles and instantiates a
WebAssembly module directly from a streamed underlying source. This is the most
efficient, optimized way to load wasm code.
The WebAssembly.validate()
function validates a given typed array of
WebAssembly binary code, returning whether the bytes form a valid wasm
module (true
) or not (false
).
The GlobalDescriptor
describes the options you can pass to
new WebAssembly.Global()
.
The MemoryDescriptor
describes the options you can pass to
new WebAssembly.Memory()
.
A ModuleExportDescriptor
is the description of a declared export in a
WebAssembly.Module
.
A ModuleImportDescriptor
is the description of a declared import in a
WebAssembly.Module
.
The TableDescriptor
describes the options you can pass to
new WebAssembly.Table()
.
The value returned from WebAssembly.instantiate
.
