Crate cranelift_wasm
source ·Expand description
Performs translation from a wasm module in binary format to the in-memory form
of Cranelift IR. More particularly, it translates the code of all the functions bodies and
interacts with an environment implementing the
ModuleEnvironment
trait to deal with tables, globals and linear memory.
The crate provides a DummyEnvironment struct that will allow to translate the code of the
functions but will fail at execution.
The main function of this module is translate_module.
Structs
Index type of a defined function inside the WebAssembly module.
This
ModuleEnvironment implementation is a “naïve” one, doing essentially nothing and
emitting placeholders when forced to. Don’t try to execute code translated for this
environment, essentially here for translation debug purposes.Index type of a function (imported or defined) inside the WebAssembly module.
WebAssembly to Cranelift IR function translator.
WebAssembly global.
Index type of a global variable (imported or defined) inside the WebAssembly module.
WebAssembly linear memory.
Index type of a linear memory (imported or defined) inside the WebAssembly module.
Index type of a signature (imported or defined) inside the WebAssembly module.
WebAssembly table.
Index type of a table (imported or defined) inside the WebAssembly module.
Enums
Globals are initialized via the four
const operators or by referring to another import.The value of a WebAssembly global variable.
How to return from functions.
A WebAssembly translation error.
Traits
Environment affecting the translation of a single WebAssembly function.
An object satisfying the
ModuleEnvironment trait can be passed as argument to the
translate_module function. These methods should not be called
by the user, they are only for cranelift-wasm internal use.Functions
Translate a sequence of bytes forming a valid Wasm binary into a list of valid Cranelift IR
Function.Type Definitions
A convenient alias for a
Result that uses WasmError as the error type.
