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.
