Module wasmtime_environ::wasm
source · [−]Modules
A simple event-driven library for parsing WebAssembly binary files (or streams).
Macros
Return an Err(WasmError::Unsupported(msg)) where msg the string built by calling format!
on the arguments to this macro.
Structs
Index type of a passive data segment inside the WebAssembly module.
Index type of a defined function inside the WebAssembly module.
Index type of a defined global inside the WebAssembly module.
Index type of a defined memory inside the WebAssembly module.
Index type of a defined table 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 passive element segment inside the WebAssembly module.
WebAssembly event.
Index type of an event inside the WebAssembly module.
Index type of a function (imported or defined) inside the WebAssembly module.
Contains information passed along during a function’s translation and that records:
WebAssembly to Cranelift IR function translator.
Temporary object used to build a single Cranelift IR Function.
A WebAssembly global.
Index type of a global variable (imported or defined) inside the WebAssembly module.
Index type of an instance inside the WebAssembly module.
Specialized index for just instance types.
WebAssembly linear memory.
Index type of a linear memory (imported or defined) inside the WebAssembly module.
Index type of a module inside the WebAssembly module.
Contains information decoded from the Wasm module that must be referenced during each Wasm function’s translation.
Specialized index for just module types.
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.
Index type of a type inside the WebAssembly module.
WebAssembly function type – equivalent of wasmparser’s FuncType.
Enums
An entry in the alias section of a wasm module (from the module linking proposal)
An index of an entity.
A type of an item in a wasm module where an item is typically something that can be exported.
Globals are initialized via the const operators or by referring to another import.
The value of a WebAssembly global variable.
How to return from functions.
WebAssembly table element. Can be a function or a scalar type.
A WebAssembly translation error.
WebAssembly value type – equivalent of wasmparser’s Type.
Constants
Version number of this crate.
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.
Environment affecting the translation of a WebAssembly.
Functions
Create a Block with the given Wasm parameters.
Get the parameter and result types for the given Wasm blocktype.
Turns a wasmparser f32 into a Cranelift one.
Turns a wasmparser f64 into a Cranelift one.
Special VMContext value label. It is tracked as 0xffff_fffe label.
Helper function translating wasmparser possible table types to Cranelift types when possible, or None for Func tables.
Translate a sequence of bytes forming a valid Wasm binary into a list of valid Cranelift IR
Function.
Helper function translating wasmparser types to Cranelift types when possible.
Type Definitions
A convenient alias for a Result that uses WasmError as the error type.
