Crate wasmer_compiler

The wasmer-compiler crate provides the necessary abstractions to create a compiler.

It provides an universal way of parsing a module via wasmparser, while giving the responsibility of compiling specific function WebAssembly bodies to the Compiler implementation.

Re-exports

pub use frame_info::FRAME_INFO;

pub use frame_info::FRAME_INFO;

Modules

object

Object creator for Wasm Compilations.

serialize

types

Types for compilation.

Structs

ArtifactBuild

A compiled wasm module, ready to be instantiated.

ArtifactBuildFromArchive

A compiled wasm module that was loaded from a serialized archive.

BaseTunablesNon-WebAssembly

Tunable parameters for WebAssembly compilation. This is the reference implementation of the Tunables trait, used by default.

FRAME_INFONon-WebAssembly

This is a global cache of backtrace frame information for all active

Features

Controls which experimental features will be enabled. Features usually have a corresponding WebAssembly proposal.

FunctionExtentNon-WebAssembly

Represents a continuous region of executable memory starting with a function entry point.

GlobalFrameInfoRegistrationNon-WebAssembly

An RAII structure used to unregister a module’s frame information when the module is destroyed.

ModuleFromArchive

Module loaded from an archive. Since CompileModuleInfo is part of the public interface of this crate and has to be mutable, it has to be deserialized completely.

Enums

CompiledFunctionFrameInfoVariantNon-WebAssembly

The variant of the compiled function frame info which can be an owned type

FrameInfosVariantNon-WebAssembly

The variant of the frame information which can be an owned type or the explicit framed map

InstantiationError

An error while instantiating a module.

LinkError

The WebAssembly.LinkError object indicates an error during module instantiation (besides traps from the start function).

Constants

VERSION

Version number of this crate.

Traits

ArtifactCreate

An Artifact is the product that the Engine implementation produce and use.

TunablesNon-WebAssembly

An engine delegates the creation of memories, tables, and globals to a foreign implementor of this trait.

Upcastable

Trait needed to get downcasting of Engines to work.

Functions

get_trace_and_trapcodeNon-WebAssembly

Given a Trap, this function returns the Wasm trace and the trap code.

register_frame_infoNon-WebAssembly

Registers a new compiled module’s frame information.

resolve_importsNon-WebAssembly

This function allows to match all imports of a ModuleInfo with concrete definitions provided by a Resolver.

Type Aliases

Addend

Addend to add to the symbol value.

CodeOffset

Offset in bytes from the beginning of the function.
