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.
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.
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.
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.
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.
