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.

Structs

• BaseTunables
  Tunable parameters for WebAssembly compilation. This is the reference implementation of the Tunables trait, used by default.
• FRAME_INFO
  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.
• FunctionExtent
  Represents a continuous region of executable memory starting with a function entry point.
• GlobalFrameInfoRegistration
  An RAII structure used to unregister a module’s frame information when the module is destroyed.

Enums

• 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.
• Tunables
  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_trapcode
  Given a Trap, this function returns the Wasm trace and the trap code.
• register_frame_info
  Registers a new compiled module’s frame information.
• resolve_imports
  This function allows to match all imports of a ModuleInfo with concrete definitions provided by a Resolver.

Type Definitions

• Addend
  Addend to add to the symbol value.
• CodeOffset
  Offset in bytes from the beginning of the function.
