Wasmer API
Re-exports
pub use wasmer_compiler::wasmparser; |
Modules
internals | We use the internals module for exporting types that are only
intended to use in internal crates such as the compatibility crate
|
vm | We use the vm module for re-exporting wasmer-vm types |
Macros
imports | Generate an |
Structs
Array | The |
Atomically | Atomically. |
Bytes | Units of WebAssembly memory in terms of 8-bit bytes. |
Cranelift | Global configuration options used to create an [ |
ExportType | A descriptor for an exported WebAssembly value. |
Exports | Exports is a special kind of map that allows easily unwrapping the types of instances. |
ExportsIterator | An iterator over exports. |
Features | Controls which experimental features will be enabled. Features usually have a corresponding WebAssembly proposal. |
FrameInfo | Description of a frame in a backtrace for a |
Function | A WebAssembly |
FunctionType | The signature of a function that is either implemented in a Wasm module or exposed to Wasm by the host. |
Global | A WebAssembly |
GlobalType | WebAssembly global. |
HostRef | Represents a piece of data located in the host environment. |
ImportObject | All of the import data used when instantiating. |
ImportObjectIterator | Iterator for an |
ImportType | A descriptor for an imported value into a wasm module. |
Instance | A WebAssembly Instance is a stateful, executable
instance of a WebAssembly |
Item | The |
JIT | The JIT builder |
JITArtifact | A compiled wasm module, ready to be instantiated. |
JITEngine | A WebAssembly |
LazyInit | Lazily init an item |
LocalFunctionIndex | Index type of a function defined locally inside the WebAssembly module. |
Memory | A WebAssembly |
MemoryType | A descriptor for a WebAssembly memory type. |
MemoryView | A view into a memory. |
MiddlewareReaderState | The state of the binary reader. Exposed to middlewares to push their outputs. |
Module | A WebAssembly Module contains stateless WebAssembly code that has already been compiled and can be instantiated multiple times. |
NamedResolverChain | A |
NativeFunc | A WebAssembly function that can be called natively (using the Native ABI). |
Pages | Units of WebAssembly pages (as specified to be 65,536 bytes). |
RuntimeError | A struct representing an aborted instruction execution, with a message indicating the cause. |
Store | The store represents all global state that can be manipulated by WebAssembly programs. It consists of the runtime representation of all instances of functions, tables, memories, and globals that have been allocated during the lifetime of the abstract machine. |
Table | A WebAssembly |
TableType | A descriptor for a table in a WebAssembly module. |
Target | This is the target that we will use for compiling the WebAssembly ModuleInfo, and then run it. |
Triple | A target "triple". Historically such things had three fields, though they've added additional fields over time. |
Tunables | Tunable parameters for WebAssembly compilation. |
WasmPtr | A zero-cost type that represents a pointer to something in Wasm linear memory. |
Enums
Architecture | The "architecture" field, which in some cases also specifies a specific subarchitecture. |
CallingConvention | The calling convention, which specifies things like which registers are used for passing arguments, which registers are callee-saved, and so on. |
CpuFeature | The nomenclature is inspired by the |
DeserializeError | The Deserialize error can occur when loading a compiled Module from a binary. |
Export | The value of an export passed from one instance to another. |
ExportError | The |
Extern | An |
ExternRef | Represents an opaque reference to any data within WebAssembly. |
ExternType | A list of all possible types which can be externally referenced from a WebAssembly module. |
GlobalInit | Globals are initialized via the |
HostEnvInitError | An error while initializing the user supplied host env with the |
InstantiationError | An error while instantiating a module. |
LinkError | The WebAssembly.LinkError object indicates an error during module instantiation (besides traps from the start function). |
MemoryError | Error type describing things that can go wrong when operating on Wasm Memories. |
Mutability | Indicator of whether a global is mutable or not |
OperatingSystem | The "operating system" field, which sometimes implies an environment, and sometimes isn't an actual operating system. |
SerializeError | The Serialize error can occur when serializing a compiled Module into a binary. |
Type | A list of all possible value types in WebAssembly. |
VMExport | The value of an export passed from one instance to another. |
ValType | A list of all possible value types in WebAssembly. |
Constants
HOST | The |
VERSION | Version number of this crate. |
WASM_MAX_PAGES | The number of pages we can have before we run out of byte index space. |
WASM_MIN_PAGES | The minimum number of pages allowed. |
WASM_PAGE_SIZE | WebAssembly page sizes are fixed to be 64KiB. Note: large page support may be added in an opt-in manner in the future. |
Traits
ChainableNamedResolver | A trait for chaining resolvers together. |
