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

• Compilation
  The result of compiling a WebAssembly module’s functions.
• CompileModuleInfo
  The required info for compiling a module.
• CompiledFunction
  The result of compiling a WebAssembly function.
• CompiledFunctionFrameInfo
  The frame info for a Compiled function.
• CustomSection
  A Section for a Compilation.
• CustomSectionRef
  See CustomSection.
• Dwarf
  The DWARF information for this Compilation.
• Features
  Controls which experimental features will be enabled. Features usually have a corresponding WebAssembly proposal.
• FunctionAddressMap
  Function and its instructions addresses mappings.
• FunctionBody
  The function body.
• FunctionBodyRef
  See FunctionBody.
• InstructionAddressMap
  Single source location to generated address mapping.
• JumpTable
  An opaque reference to a jump table.
• MiddlewareError
  A error in the middleware.
• Relocation
  A record of a relocation to perform.
• SectionBody
  The bytes in the section.
• SectionIndex
  Index type of a Section defined inside a WebAssembly Compilation.
• SourceLoc
  A source location.
• Target
  This is the target that we will use for compiling the WebAssembly ModuleInfo, and then run it.
• TrampolinesSection
  Trampolines section used by ARM short jump (26bits)
• TrapInformation
  Information about trap.
• Triple
  A target “triple”. Historically such things had three fields, though they’ve added additional fields over time.

Enums

• Architecture
  The “architecture” field, which in some cases also specifies a specific subarchitecture.
• BinaryFormat
  The “binary format” field, which is usually omitted, and the binary format is implied by the other fields.
• CallingConvention
  The calling convention, which specifies things like which registers are used for passing arguments, which registers are callee-saved, and so on.
• CompileError
  The WebAssembly.CompileError object indicates an error during WebAssembly decoding or validation.
• CompiledFunctionUnwindInfo
  Compiled function unwind information.
• CompiledFunctionUnwindInfoRef
  See CompiledFunctionUnwindInfo.
• CpuFeature
  The nomenclature is inspired by the cpuid crate. The list of supported features was initially retrieved from cranelift-native.
• CustomSectionProtection
  Custom section Protection.
• Endianness
  The target memory endianness.
• OperatingSystem
  The “operating system” field, which sometimes implies an environment, and sometimes isn’t an actual operating system.
• ParseCpuFeatureError
  The error that can happen while parsing a str to retrieve a CpuFeature.
• PointerWidth
  The width of a pointer (in the default address space).
• RelocationKind
  Relocation kinds for every ISA.
• RelocationTarget
  Destination function. Can be either user function or some special one, like memory.grow.
• WasmError
  A WebAssembly translation error.

Constants

• VERSION
  Version number of this crate.

Type Definitions

• Addend
  Addend to add to the symbol value.
• CodeOffset
  Offset in bytes from the beginning of the function.
• CustomSections
  The custom sections for a Compilation.
• Functions
  The compiled functions map (index in the Wasm -> function)
• JumpTableOffsets
  Code offsets for Jump Tables.
• Relocations
  Relocations to apply to function bodies.
• WasmResult
  A convenient alias for a Result that uses WasmError as the error type.
