Crate wasmedge_sys
source ·Expand description
§Overview
The wasmedge-sys crate defines a group of low-level Rust APIs for WasmEdge, a light-weight, high-performance, and extensible WebAssembly runtime for cloud-native, edge, and decentralized applications.
For developers, it is strongly recommended that the APIs in wasmedge-sys
are used to construct high-level libraries, while wasmedge-sdk
is for building up business applications.
- Notice that wasmedge-sys requires Rust v1.71 or above in the stable channel.
§Build
To use or build the wasmedge-sys
crate, the WasmEdge
library is required. Please refer to WasmEdge Installation and Uninstallation to install the WasmEdge
library.

The following table provides the versioning information about each crate of WasmEdge Rust bindings.

- Defines WasmEdge CallingFrame.
- Defines WasmEdge instance structs, including Function, Global, Memory, Table, and etc.

Structs§
- Represents a calling frame on top of stack.
- Compiler
aot
Defines WasmEdge ahead-of-time(AOT) compiler and the relevant APIs. - Defines Config struct used to check/set the configuration options.
- Defines an execution environment for both pure WASM and compiled WASM.
- Defines the types of the exported wasm values.
- Struct of WasmEdge FuncType.
- Defines a host function.
- Defines a WebAssembly global variable, which stores a single value of the given type and a flag indicating whether it is mutable or not.
- Struct of WasmEdge GlobalType.
- An ImportModule represents a host module with a name. A host module consists of one or more host function, table, memory, and global instances, which are defined outside wasm modules and fed into wasm modules as imports.
- Defines the types of the imported wasm value.
- Loader is used to load WASM modules from the given WASM files or buffers.
- Defines a WebAssembly memory instance, which is a linear memory described by its type. Each memory instance consists of a vector of bytes and an optional maximum size, and its size is a multiple of the WebAssembly page size (64KiB of each page).
- Struct of WasmEdge MemoryType.
- Defines compiled in-memory representation of an input WASM binary.
- Struct of WasmEdge Statistics.
- The Store is a collection of registered modules and assists wasm modules in finding the import modules they need.
- Struct of WasmEdge TableType.
- Struct of WasmEdge Validator.
- A WasiModule is a module instance for the WASI specification.
- Defines a WebAssembly value.
Traits§
- The object as an module instance is required to implement this trait.
Type Aliases§
- Defines a reference to a host function.
- WasiCtx
async
and LinuxType of wasi context that is used to configure the wasi environment.
